Fiberglass

Fiberglass is a composite material made from glass fibers embedded in resin. Finished pieces usually have a smooth resin or gelcoat surface rather than exposed fibers.

Fiberglass paint compatibility

Acrylic paint can work on prepared fiberglass, but the primer and topcoat must be compatible with the existing resin or gelcoat.
