Alumabrite will not harm newer polyurethane paints or gelcoat on fiberglass. It can cause some streaking on anti-fouling bottom paints and may attack some older paints, especially if the composition of the paint is unknown. Before using Alumabrite, or any other strong cleaner for that matter, near any paint or gelcoat, I suggest that you test it on a small inconspicuous spot to see if there are any negative effects, before doing the entire boat.
Thanks for your question,
