I sprayed U-Pol Raptor bedliner in my Alfa Spider. This was based on what the guys at Vintage Kustoms do in Burlington WA. Sprays nicely with special gun and you can put down a nice textured layer or two as deep as you want. FWIW, I have a couple cans left that I'll sell for 20 each, black not tintable. other folks I know have used Lizard skin which they like, but seems to be more difficult to get into nooks and crannies Raptor sprays into crevices and gaps well.
