“My boat has gelcoat cracks on the deck and hull. There are also little bumps on the hull below the waterline, some have broken open; can water get into the fiberglass? What should I do?” Carl D. – Malta, NY
The gelcoat on a boat is a polyester based resin; it is a very porous material. It never stops curing; the older it gets the more brittle it becomes. The constant exposure to moisture, dirt and UV sunrays can break it down.
