The paint features a gel-like outer layer of grippy polyrotaxane, the chemical structure that's able to reconfigure itself back to its original layout and shape whenever it is scratched.

According to Nissan, minor scratches can be healed within an hour, but more serious scuffing can take up to a week to disappear. The rest of the case, which fits both iPhone 4 and 4S models, is made out of hardy ABS plastic that's widely used throughout the automotive industry.

Development of Scratch Shield paint began in 2005 in collaboration with the University of Tokyo and Advanced Softmaterials, and is currently applied to the company's Murano and X-Trail four-wheel drives, as well as the 370Z sports coupe.

Nissan's European arm has produced an initial run of prototype cases, which will be distributed and tested by a select group of customers and journalists. Should results and demand prove to be encouraging, then the company is hoping to have the case on sale later in 2012.
