Are you sure its paint and not gelcoat that''s crazed? Fiberglass boats don''t necessarily get painted at the factory when new (the various colors of boat hulls that you see are actually dyes that are added to an outer coat of resin applied to the hull during construction), so what you may be seeing is crazed gelcoat. If so, painting would probably be a waste of time, as the cracks in the gelcoat would need to be properly repaired first.
