My friend who worked at Boston Whaler Rockland MA factory from 1959-mid 1980's, and has more than 55 years of fiberglass/gelcoat repair experience, says that you can repair gelcoat cracks but the cracks will return after a period of time. Of course, it depends on the depth of the gelcoat cracks. sometimes you can sand out a crack in gelcoat, i.e., like I experienced with my BW17 Striper hull; this is the case if the crack does not go all the way through the gelcoat. Gelcoat thickness can be min 1/16 inch in some areas of the hull to 1/4 inch in the chine areas.
