I'm thinking about doing the load bed of my pickup with Upol Raptor. What surface prep does it need when being rolled onto the original paint? There is no rust or chips in the paint so would I need a primer or can it go straight on?
I've used Raptor on one of my projects. I used it over some epoxy primer, with just a surface key. I can't see why it would be any different going over paint. I would use a coarse paper, since Raptor is textured you wont notice the scratches and you should get better adhesion.
