they also make plastic prep paint that preps the plastic so you can use a variety of paints on top. sem is one of the best to use. i think it is called plastic adhesion promoter.
Yep. The adhesion promoter stuff I used was called Bulldog. Great stuff. It goes on clear too. I used it for my door panels and my convertible rear panels, armrest, etc with a custom factory looking color I got mixed at Carquest.
SEM is really good for fabric. Used to change my carpet color from gold to black on my dad's chevelle
