Can anyone expound on the prep and paint of Vinyl (not flexible) parts such as Challenger Door panels? I know to use SEM cleaner, primer and paints, but how to prep and how to mimick the texture?  

HOLD ON! I found what I needed on FORDMUSCLE.com! Everything you (or me) needs to know about SEM vinyl paints and prep - check it out when you need to re-caot plastic parts!
