I have never had any success painting plastic parts. I have followed the guidance found everywhere: scuff sand, clean with grease remover, prep with adhesion promoter, etc. and there are always portions that just don’t take the paint just right. I guess it doesn’t help that I was trying to paint my headlight bezels that are 35 years old and the plastic is well-cooked (but if they didn’t look that way, I wouldn’t want to clean them up). What’s the secret?

Surface prep is the key, I’ve had good results with Restoration Shop
grease and wax remover.
scuff with a fine to medium pad (scotchbright)
Use a bonding type paint like ColorBond
Seal with light coats of Mat or Satin Clear coat

I just painted a bunch of plastic parts for our classic car. Getting years of Armour all off of the center console took a lot of time and patience. Prep is so important like @FireTruck1984 said. Primer or another type of adhesion product is also helpful.
