It's at Home Depot and is a contact cement/glue. It may take a few tries to get it to bind up the decaying foam but figure 20 bucks for the can at most. If you DIY, you just need this stuff and patience. I found to keep it off my fingers I used a plastic shopping bag when smoothing the fabric back into place.
The fabric on the interior door in between the window controls and doorhandle is coming off, reviewing the orange stuff behind it. It's coming off on the fabric in spotty patches, and feels kind of like Clay to the touch. The passenger side is also starting to bubble and will probably eventually peel as well.
