I have a fiberglass shower that I want to paint. What is the best kind of paint to use for this project?

I have done this a few times with a marine epoxy. The most important thing is the prep. I cleaned real good with Goof Off and sanded to dull the finish. I have no idea how long this lasted because I sold the houses after doing it, but it looked great.

I think that Rust-Oleum has a paint for bathtubs that is supposed to work on fiberglass. I think that their website is rustoleum.com.

Yeah, sand it down good, and then a quality, non latex paint.
