OOps Corrected Subject line  !

Does anyone have a recommendation on paint to use for fiberglass bumpers
and plastic front grill pieces on a Vanagon ?

I'm about to give   "Rust-Oleum Trim & Bumper Paint"   a try but thought
I'd ask for opinions before I regret using the wrong type of coating.

I've seen repainted fiberglass bumpers ( black ) that looked good but
have not heard how they are done.

Thanks   -john
