There has been a few posts from people wanting to know how to prep plastic for painting. Yes it can be tough getting the paint to properly adhere to what I call bleach bottle plastic. An old time painter that was in the lime light 40 years ago,and still is, told me this little trick. Don't laugh, I know I did when he told me. I thought he was kidding me. Get your self a hardware store propane torch,and just waft it lightly over the surface. Go lightly you don't want to end up with true fire. What this does is that it slightly oxidizes the surface. Then hit it with a scotch brite pad. Wash the part with soap and water then dry it off. Don't use air as this will or could cause static to build up on the surface. After all this hit it with adhesion promoter and away you go. The paint will adhere like crazy,and you won't have any delam down the road. I've done this on plastic fenders, and twisted them every which way and could not get the paint to break loose. Didn't even crack. Give it a try.
