Got it. The paint will stick to the plastic just fine though as long as you prep it right, especially since it's already been painted. You won't be painting to the plastic, you'll be painting to the primer as long as you don't sand all the way through. Good luck with whatever you do, hope it comes out great.I agree with you and should've worded all this differently from the beginning. I was worried about wasting the expensive paint due to it not sticking to the plastic, so I tested the white I had on a little spot. It was so close that I decided to just go ahead and do it. I figured worst case, I'll just do it over.
