I clean the plastic very well and use paint made for spraying vinyl ulpolstery. It will tend to fade a little in time but I will respray it again in about 5 years or so.

This is the point. Get a paint that is SPECIFICALLY FORMULATED for use with plastics. Any other "compatible" paint will be an experiment. DO NOT take the advise of a yahoo at AutoZone or base your decision on a label claim. Get a professional product designed for your specific material.
[/quote] That would be a good idea if they made paint specifically for plastic. Nothing is a guarentee when painting plastic , thats why they mold plastic in colors. Most interior paint for plastic is nothing more than just paint with some flattening agent in it. The adhesion promoter will soften the plastic so the paint will adhere to it. When you paint a rubber bumper or a plastic panel for a Saturn or any other plastic or rubber part, you don't call up autobody supply and order rubber bumper paint or plastic panel paint. You just order paint! It is up to the guy using it to know how to make it stick or flex. Yes there are types of plastic that will melt when you try to spray with automotive paint but all plastic that has a automotive purpose will be fine. Use the adhesion promoter ! Clean the plastic well , re clean with PPG's DX 103 multi prep ( some kind of alcohol based cleaner ), spray your adhesion promoter on the plastic, let it sit a few minutes, paint. You should be as good as it is going to get.
Don't sand the plastic ! If you do the adhesion promoter will swell the scratches and it will look like you sanded it with 80 grit sandpaper. Good luck
