I'm not sure how the finish is on the painted plastic, but typically when you paint over paint, you want to do a little sanding first. The surface needs to have some texture for the paint to hold on to. Not like you're using steel wool, just lightly sand it until the existing paint doesn't have any shine - then you can paint over it.

yea make sure theres not cracks on the old paint or itll peeeeeeeel. Peeeeeeling is not good.

Definitely sand it. I tried just repainting over my existing paint when I did it on my Corolla and it did not look good at all.

I agree.. Sand it wil 2,000 grit then use a paint adhesive so the paint sticks well.

as long as your original paint job was good, sanding and repainting is fine. I would strip the old paint personally, just because it would suck to have the old paint peal and ruin the top paint. But it shouldn't be a prob if the first paint is stuck on well with no signs of peeling.
