Jet Ski & Personal Watercraft Fiberglass Repair

On a PWC, cracks tend to show up where the hull takes the most pounding, and filler alone just cracks again through the new gelcoat. We grind back to sound laminate, rebuild with fresh layers of biaxial cloth and epoxy or vinyl ester resin, then fair, color-match, wet sand and polish, so the repair is strong first and invisible second.

A hard hit on a dock, rock or another craft can punch through a PWC hull or gouge deep into the laminate, letting water inside. We grind back to solid glass, laminate new biaxial cloth, fair it to the hull’s true shape, and spray gelcoat matched to the factory tone. Insurance claims are welcome.

Running up onto sand and shell grinds away the keel and the area around the intake grate, and once the gelcoat is gone the fiberglass is open to water. We grind back to sound laminate, build the worn areas up with new fiberglass, fair them to the hull’s original shape and finish in color-matched gelcoat.

The pump and ride plate area takes the full push of the jet every time you accelerate, so stress cracks around the transom and ride plate are common on hard-ridden skis. We remove the cracked and separated laminate, rebuild the area with new fiberglass cloth, then fair and gelcoat it to match the hull.
