Listen to the hype about ceramic auto paint coatings and you might get the idea that a ceramic top coat will protect your vehicle from falling tree limbs. It won't. The best ceramic coatings will give your car or truck its best defense against settling airborne chemicals and pollutants, tree sap, road and sea salt, bird poop and the sun's harmful ultraviolet rays. They'll also deliver a gorgeous sheen that's hard to beat.

Think of ceramic coating as a harder, more protective clear coat for your paint's clear coat. It's the best, most durable way to protect your vehicle's finish, short of a full transparent film wrap, and its hydrophobic (water sheeting) properties make cleaning much, much easier. A properly applied ceramic coating can last for years.

The best ceramic coatings require differing amounts of time and energy to apply, but all require some level of sweat equity and commitment (there's a reason automotive detailing shops get big bucks to professionally apply ceramic). There's a lot of white noise about ceramic coatings and literally hundreds of products to choose from. We've waded through the hype and chosen the best OTC ceramic coatings for a variety of circumstances, purposes and commitment levels based on expert knowledge and opinion, user ratings and personal experience. Click through our best ceramic coatings to understand your options, then read on for a primer on what this amazing technology will and won't do for your vehicle and how best to use it.

Weiruixin 10H Ceramic Coating 3.0 shown on a blue background

This product originates in China and delivers pro-grade chemistry for the price of good, easy-application, consumer-grade detailing products, with applicator, towels, etc. in the package. Weiruixin claims 10H Ceramic Coating 3.0 has an industry best 10H hardness rating and remains bonded at temperatures up to 1,400 degrees Fahrenheit. It guarantees its hydrophobic properties for at least two years... or your money back.

We wouldn't want to have to chase that $25, but the indicators suggest this could be a good product for not much money, if you're willing to make it work. Experience tells us that it won't be easy to use. The thick fluid will be temperature sensitive, demanding room-temperature, no-dust application conditions and you'll have to keep your car dry and shaded for seven days for it to fully cure. If you lack pro-grade skills, better to choose something like our best cheap and easy ceramic coating. You'll be much happier with the process and maybe even with the results.

Mothers CMX 3-in-1 Polish Coating on a pink background

Like our best minimalist ceramic coating prep (Mothers CMX Surface Prep), CMX Ceramic 3-in-1 Polish & Coat removes grease, old wax and other chemical residue in advance of your ceramic coating application. Yet 3-in-1 adds a light polishing compound, so with a dose more elbow grease or a polishing wheel, it can also remove swirl marks, light scratches, oxidation and other imperfections in the paint.

Better still, Mothers CMX Ceramic 3-in-1 Polish & Coat includes mineral oxides like those in the ceramic coating itself, so it leaves a nice, hard gloss when you're finished. It's hardy enough to leave as it is, but it also provides a fantastic primer coat for a full ceramic coating on top. It won't deteriorate an existing ceramic coating, either, and that makes it a great refresher to invigorate and deepen a good coating that's a couple years old with less work (and cost) than starting from scratch.

Ceramic coatings 101

Somewhere in or under your automobile, there's almost certainly some ceramic coating. Automakers have been using it for years because it's the best protective finish for a variety of parts, including wheel hubs, interior trim bits and things you'll see if you lift the hood. You just won't have ceramic coating on your vehicle's finish paint unless you put it there yourself.

Ceramic coatings can have different names -- nano ceramic, quartz or silica coatings -- and come in various forms. There are thermal sprays, dry powder coatings and wet chemical sprays or liquids. There are different auto-detailing ceramics for different surfaces like wheels, paint, windows or trim. In this report we'll focus on the paint, though some products will work on all of the above. Some of them aren't ceramic coatings in the original form. They're hybrids manufactured like more conventional auto waxes and infused with the key ingredient that makes ceramic coatings "ceramic."

That ingredient is silicon dioxide (SiO2), which bonds the coating at a molecular level to itself and the paint underneath, then cures to form a hard, hydrophobic (impenetrable to water) layer on top of the paint. The silicon dioxide is extracted from natural materials like quartz or sand. Over the years, some ceramic coating manufacturers have added titanium dioxide (Ti02) or more complex silicon compounds such as silicon nitride (Si3N4 9) and silicon carbide (SiC) to their formulae. These can increase the performance of the coating.

Any ceramic coating worth the name will have at least 5% silicon dioxide. The best consumer-grade ceramics have SiO2 concentrates in the 70-80%range, though these can also be the most difficult to apply. Professional detailers and installers typically use ceramic coatings with SiO2 concentrations between 93 and 97%. Other things equal, the higher the SiO2 percentage, the stronger and more durable the coating becomes, and the more money it costs.

In ceramic coatings, other things are rarely equal. The overall performance and price of the product is at least as important as the amount of silicon dioxide. Every ceramic coating also has polymers (more conventional bonding chemicals), glossing agents, curing compounds and or other ingredients. While most manufacturers keep their exact formula proprietary, their products must do more than protect. They must also maximize shine and make application consistent, if not necessarily easy. While the level of silicon dioxide is important to a ceramic coating's overall durability, it's not the only thing that determines a coating's overall performance, in terms of how it looks on your car and how easy or difficult it is to put there.

Ceramic coatings are sometimes rated with a number before the letter H like 8H or 9H. Contrary to published claims and popular belief, this is not a rating on the Moh scale, which is used by geologists to rank mineral hardness from 1 to 10 (the surface of a copper penny is about 3.5H on the Moh scale, while a diamond is 10H). Rather, the ratings for ceramic coatings will be based on the Wolff-Wilborn Pencil Hardness Test. A pencil hardness test drags increasingly hard graphite pencils across the surface of a coating. The resultant number identifies the softest pencil that will leave a scratch on the coating. A 9H in a pencil hardness test demonstrates about the same surface hardness as the copper penny on the Moh scale, and while that's not diamond grade, it's still pretty darn hard. By pencil hardness, the standard clear coat paint on your car or truck is somewhere between 2H and 4H. That means a 9H ceramic coating is 2.25 to 4.5 times harder to scratch.

Over-the-counter ceramic coatings are, obviously, intended for use by DIY auto detailers. In the simplest terms, application is similar to traditional automotive wax: You spread the ceramic on in some fashion and then buff it (though not necessarily off). Yet anyone who's done much automobile waxing knows the simplest terms don't fully explain the level of energy required. The best do-it-yourself ceramic coatings and the best results demand some level of sweat equity, in both surface preparation and application. The best in terms of durability or long-term protection are usually the most demanding. If you mess a high-grade ceramic coating up, it will be really, really hard to get off.

It's no coincidence that high-end detailing shops (sometimes called auto spas) have boomed in the era of ceramic coatings. The good shops know what they're doing and they can almost certainly do it better than you can. There are nonetheless a range of great consumer-grade ceramic coatings out there, suitable for everyone from raw DIY detailers to those with pro-grade skills. Those products can leave the paint on your car or truck looking gorgeous... and a you that's proud of what you accomplished, wherever you rank in the detailing-skills pecking order.

We'll get to the details of ceramic coating preparation and application shortly, but if you plan to do it yourself you need to start by gauging how much time and energy you're willing to commit. And by not overestimating your skills. And by considering what you're willing to do if it goes wrong.

First, let's get specific about the real benefits of ceramic coatings and the myths.

What ceramic coatings will (and won't) do

The best ceramic coatings will give your car or truck an incredible shine and probably a better shine than it's ever had before. Professional detailers and some car geeks know that shines can be different like the deep, mellow, lusty shine of perfectly applied, old-school carnauba wax or the more aggressive, wet-look shine of subsequent polymer sealants. The best ceramic coatings span a similar spectrum, but all of them will leave you looking over your shoulder and admiring as you walk away from your vehicle in a parking lot. They'll keep your car cleaner, longer and they'll make it look like you just re-waxed it every time you wash it.

At least as importantly, the best ceramic coatings will protect your car's paint better than any conventional carnauba or poly wax can. Think of any wax or sealant as a transparent sacrificial layer that can be removed or reapplied as necessary to protect the paint underneath it. Ceramic coating is just harder and less porous than more conventional waxes, so it makes it more difficult for anything that settles on the paint to penetrate or even stick. We're talking things like airborne chemicals and pollutants, overspray of any type, tree sap, bird droppings, road or sea salt or the sun's relentless UV rays. Ceramic coating is the best chemical barrier against the harmful effects of multiple substances that can damage paint and diminish its appearance over the years, even moreso if your car lives outside. It will fill the role of sacrificial layer better than any carnauba or poly was and it can do so more economically.

That's because, thanks to silicon dioxide and all that molecular bonding, ceramics stay put a lot longer. A relatively inexpensive, easy application, ceramic spray can protect for a year or so. To maintain peak performance with a traditional wax-on, wax-off carnauba or poly coat, you'll need to lay down a new layer every three or four months. The manufacturers of some more expensive ceramic liquids warranty their product for two years. (We are not weighing in on how difficult or fruitful it might be to make a claim on those warranties.) We've known consumer-grade ceramic liquids that have lasted close to five years before their hydrophobic properties start to diminish. Detailing shops in urban areas around the country, including Motor City Auto Spas in greater Detroit, will guarantee their ceramic applications five, seven or 10 years, depending on the product used.

"We'll guarantee our top product for life, if the car is relatively new, with an annual inspection and detail," says Motor City founder and CEO Matt Lifter. "Short of the annual visits we'll guarantee seven years. Not even acidic solvents like wheel or brake-dust cleaners will take it off. It's really amazing stuff."

Ceramic coating is more durable than wax or poly in another sense because it's much harder. That means it's more resistant to light scratches or paint swirls (those spiraling curves that can develop in clear coat after years of washing). Indeed, a ceramic-coated vehicle that's washed properly (no drive-thrus) is nearly immune to paint swirls.

We emphasize "resistant" above because no ceramic coating is scratch proof, even if some to the wildest marketing hype suggests that it might be. Drag a key along a door panel on a ceramic-coated car and the panel will definitely scratch. Throw pebbles at it hard and it will nick. Bottom line: Ceramic-coated cars are still susceptible to rock chips. Some road rash is still likely to build up over the miles and years.

If your overriding goal is preventing rock chips or road rash, better look past ceramic coating. In the current state of auto protection, that would mean looking toward transparent film or "wraps."

Not up to speed on wraps? Vinyl auto wrap is a blend of polyvinylchloride and additives that make it flexible and resistant to UV light and sometimes add color. The additives are blended, dropped onto moving sheets of PVC, then baked and cured. Transparent wrap is virtually invisible on your car's paint, except for barely perceptible edges where the wrap might end and give way to unprotected paint, and it provides an actual, physical cushioning barrier between the paint and whatever the road throws at it. Good wrap will self-heal, so if a high-velocity pebble takes a divot out of the protective barrier, light and heat will actually close and smooth it again.

Wrap will get you closer to proofing your car from scratches, rock chips or road rash than any ceramic coating can. It is also considerably more expensive than ceramic (the product) and significantly more difficult to apply. While some brave amateurs have tried, we wouldn't think about doing this ourselves.

Before we get to the process of applying ceramic, there's one more myth to address: Yes, even with the best ceramic coating, you will still have to wash your car.

We're compelled to make this point because a lot of the hype out there seems to suggest you'll never have to wash your car again. We assure you you'll have to do it less often, but dirt, road salt and other appearance-marring substances will eventually build up on the ceramic. The good news, beyond the fact that you'll wash it less, is that your ceramic coated vehicle should be much easier to wash than it was before the ceramic coating: generally no repeated rubbing back and forth over sticky, embedded stuff (which is another reason ceramic can keep swirl marks to a minimum) and usually more like a wipe and rinse. Indeed, some ceramic manufactures promise that, with proper application and sufficient water pressure, anything on your paint will rinse off without rubbing. Finally, know that washing can still leave water spots on ceramic coated cars, depending on the mineral content in your water source. Always towel dry.

On to the work at hand.

Layin' it down

Professional-grade ceramic coatings are usually thick, almost glue-like and often require more than one step in the curing process. Consumer-grade ceramics are generally more forgiving to apply, though the most durable can be tricky. If you've browsed our best list, you've seen that there are several types of over-the-counter ceramic coatings. Even the most modestly priced, easiest-to-apply ceramics should outperform comparably priced conventional waxes when it comes to protection and longevity.

Whichever you choose, you must understand the first rule of ceramic coatings (or conventional carnauba and poly waxes, for that matter): surface or paint preparation matters at least as much as the coating itself, and more so if the paint is in poor shape to begin with. The coating simply protects and shines whatever is underneath and it will last longest when its bond with the paint is strongest. Without any prep, you're going to make those scratches or tar flecks or bits of oxidation shine for a long time.

"I'd say on average, our prep is four to five hours," says Lifter, whose Motor City Auto Spa has been doing ceramic since the early days (ed. note: that's four or five hours from efficient, well-trained techs). "It's at least two or three times more time than the actual application. Sometimes the prep can take two full days, but we can't guarantee our product without it."

You can expect a detailing shop to undertake most or all of these steps in advance of applying ceramic coating: Washing the vehicle with an appropriate detergent and sometimes a power washer; "Claying" the paint from stem to stern, or rubbing it with soft clay slabs and a lubricating fluid to remove sap, tar and other substances from the clear coat's pores; Polishing with a compound and a power pad, which can be the trickiest part depending on the age and depth of the paint, to remove swirls, scratches and oxidation; Wiping with a chemical cleaner to remove the final vestiges of dust, grit, waxes or grease.

Now, you can do all those things yourself, if you have the inclination and fortitude and the time. It's always worth it, even on a beater with decent paint. You have to decide what you're willing to try. If it's your baby, which only leaves the garage on nice days for car meets or weekend blasts, you probably need to suck it up and try the full Cleveland. It will pay big in the final results. If it's a car you use for track days or the 10-year-old Civic that gets you reliably and satisfyingly to work and the paint still looks good, you can get away with a clay and chemical wash.

If you lean toward the less-work end of the prep spectrum, we urge you to at least undertake the chemical wash (after a good water wash). Using a product like Mothers CMX Surface Prep is essentially like washing windows. You spray it on and wipe it off, and it leaves a squeaky, chemical-free foundation that will ensure a solid bond between the ceramic and the paint. If you're up to a little more elbow grease or have an easy oscillating buffer, try something like Mothers 3-in-1 Prep & Coat. It adds a light polishing compound, so the extra rubbing will take care of a lot of the swirls and light scratches and leave a nice, polished finish.

Given the steps in proper preparation, you might surmise that the best time to apply ceramic coating is when a car is brand new or nearly so. You'd be correct. New cars (for lack of wear) require the least amount of paint correction. Detail shops will often guarantee their ceramic coatings longest when they're applied to new vehicles. If your car is already a few years old, you've got what you got. Just remember that your final ceramic-coating results will be directly related to how well the paint is prepped.

When it's time to actually apply the coating, follow these general rules. Do not apply in direct sunlight, or to paint that's hot to the touch. Do it in a garage, if there is enough light, or borrow one of those cheap outdoor canopies, if that's the next best option. Zero dust is best, and nearly impossible to achieve short of full climate-control conditions, but keep that objective in mind as you set up to start coating. An ambient temperature of about 70 F is ideal; your specific product's instructions will give you a range of acceptable application temps.

Definitely read those instructions and watch the videos on your product manufacturer's website (if available). Time spent now will be time saved during the application, and it will likely improve the end results.

Ceramic liquids are invariably what the pros use and typically have the highest silicon-dioxide concentration in consumer-grade coatings. Most come in kits with an applicator sponge and soft cloths to wrap it. Some come with microfiber towels for buffing. It never hurts to have extra application clothes.

To start, you'll wrap the applicator with one of the clothes and spot it with the ceramic coating, sometimes as little as several drops. Working in small areas, spread the coating as evenly as possible. Your product will have its own recommendation on "small," but it's not going to be more than two feet square. Over the next few minutes, depending on the product, the moisture in the ceramic will evaporate to a point where the surface gets a gleaming, almost oily look (sometimes called flashing). That's when you buff with a microfiber towel. When you're happy with what you see, start a new section.

Too little product will be better than too much. The typical 50 ml bottle of ceramic liquid can be enough for multiple cars and too much on the surface is a frequent cause of bad results. Change the applicator cloth and the polishing rags frequently, because if the coating hardens on the rags, it can definitely scratch the paint. If you have any hope of reusing the rags or applicators, throw them in a bucket of water to keep the ceramic from setting until you can wash them thoroughly.

Once you've made your way around your vehicle, leave it sitting out of the sun (and the rain) for as long as it takes for the ceramic to cure. Your product instructions will tell you specifically. Touch contact is typically allowed in 60 minutes to six hours. Liquid contact usually requires at least 24 hours, though it can take up to seven days.

"You've got to make sure the prep is good, but we already said that," veteran ceramic pro Lifter reminds home detailers. "Stay small [in the application area] as you progress, and don't think because you've successfully applied a couple small patches you can expand to bigger sections. Staying small is the best way to avoid high spots. We've had a few customers bring us messes because they lost track of that idea."

The worst-case outcome with consumer grade ceramic liquids is relatively rare, but it happens. It's usually the result of too much product applied in too big an area for the workable set time and is an uneven mess of ridges and cloudy high spots on the paint that is really, really hard to get off. Remember that this stuff is designed to last for years. The only options are looking at the mess every time you get in your car for years, or heading to a good detail or body shop, where a pro-skill polisher might get it off without wrecking the paint. That's going to cost you as much or more than what you hoped to save by applying the ceramic coating yourself.

If you're not willing to accept that risk, we suggest at least starting with one of our relatively inexpensive best ceramic sprays. The general rules are the same: Use it in the best conditions you can create, use less than you might think you need and work small. Thanks to the viscosity of the sprays, which sometimes include lubricants, and to the way they set up, they're loads more forgiving than most liquids. And they're easy enough that you can apply two or three layers in short order, as long as you respect the cure time.

Finally, whichever product you use, don't neglect your health and safety. These products are industrial-grade chemicals. You definitely want to avoid sucking the vapors into your lungs and you want to keep the liquid off your skin. Work in a well-ventilated space and wear a ventilator or a chemical mask (we should be used to masks by now). Definitely wear gloves (many kits include them); it's not a bad idea to wear a long-sleeve shirt, too.

Are you ready?

There might be a couple big-picture questions to ponder before you tear into this ceramic coating thing. If you own multiple vehicles, which do you most want to protect as best you can? How much money do you have to spend on your cars?

If the answer to that second question is as much as you need to spend, have ceramic coating professionally applied. Or maybe think about a full wrap with transparent film. It will cost more than pro-applied ceramic, but it has advantages, as previously noted.

If you only have as much money to protect your paint as you can get away with, think creatively. Maybe you pay the pros for a limited wrap (say the front fascia, door sills and rear fender bulges) and put ceramic on everything including the wrap yourself. That might be your most efficient use of resources. Or maybe you just take a nice day and apply a relatively inexpensive ceramic spray.

Unless you have the full inventory of tools, climate-controlled car space, the right skills, years of experience and a lot of time, you will not get the same results and durability as a professional establishment applying high-grade ceramic coatings. What you can get is an awesome gloss that protects much better and lasts years longer than conventional carnauba or polymer auto waxes, for up to thousands less than you might pay the pros.

That's not bad at all.

Ceramic coating FAQs

What is ceramic coating and is it worth it?

Ceramic coatings, sometimes called nano-ceramic, quartz or silica coatings, were developed in the early part of the 21st century. They're applied to automobiles in very generally the same fashion as old-school liquid or paste waxes: spread on and buff. They universally contain silicon dioxide (SiO2), derived from quartz or sand. Over the years, some manufacturers have added other mineral compounds, including titanium dioxide (Ti02) or more complex silicon compounds such as silicon nitride (Si3N4 9) and silicon carbide (SiC). These compounds bond the coating at a molecular level to itself and the paint underneath, then cure to form a hard, hydrophobic layer on the paint. It's the primary reason ceramic coatings last.

Worth it? Loaded question, but yes, ceramic coatings are worth it. The least expensive consumer-grade ceramics don't cost much more than traditional waxes and don't take any longer to apply. Properly done, they'll work better and last longer.

How much does a ceramic coating cost?

It can be $1,000 or more when it's professionally applied by product-certified auto detailers. Consumer-grade ceramics can cost in excess of $100 for top-grade durability and performance and can be tricky to apply. Ultimate results are directly related to cost or time and energy invested, yet even the least expensive, easiest-to-apply ceramics (about $20) should out-perform conventional wax of a similar price.

Is ceramic coating easy to apply?

Yes, and no. Generally, the most protective and durable ceramic coatings are the most difficult or time consuming to apply and the trickiest. Experienced do-it yourself detailers shouldn't have too much trouble with any of them, but it takes work and occasionally disasters ensue. Easy ceramic sprays or hybrids are easier than traditional wax-on, wax-off sealants to apply. They'll shine at least as well as the conventional waxes, protect better and last longer.

Just remember: the ceramic coating will only shine and protect whatever is underneath it, so you can end up with some really shiny scratches and tar flecks. Final appearance and durability are directly related to the amount of paint prep that precedes the actual coating. If your paint is in reasonably good shape, we at least recommend a spay-and-wipe prep solution, which will remove old wax and chemical residue and ensure a solid foundation that maximizes the bond between the coating and paint.

How do I maintain a ceramic-coated car?

You wash it, until the coating's hydrophobic properties start to wane and that can be years. Washing will be easier than ever: You won't have to wash your vehicle as often as you did before the ceramic coating and you shouldn't need strong detergents. Ceramic coatings work partly because far fewer substances stick to them than to old-school carnauba or polymer waxes, sort of like Teflon on a frying pan. Those substances that do settle are much more easily removed.

You can use a wash detergent that's intended for ceramic coatings, or a spray refresher on the paint as you dry. Both can extend the life of the coating itself. Either way, your vehicle will look like you just polished it when you're done. You definitely don't need to wax it once the ceramic is applied. The ceramic coating replaces wax and provides all the gloss and protection you need.

How long does ceramic coating last?

Longer than conventional wax, in the worst case. Some professional auto detailers will guarantee their ceramic coatings for the life of the car. Pro-style consumer-grade ceramics can last five years or more, properly applied. Some manufacturers guarantee these for two or three years. The easiest spray-on ceramic coatings can last a year or so, depending on whether the vehicle lives outside and they're easily layered for more durability. Conventional carnauba or poly waxes typically need to be applied every three or four months.
