    Use the correct products. The GPRs are not fiberglass and are not gelcoated. They are SMC and painted. A normal fiberglass repair won't work.

    I'll second that! I've had skis that I've had to repair or were ruined because someone used polyester resin to repair. After a while, the patch will peel like an old scab. Only use epoxy to repair SMC. Do a little internet research before you start, SMC is different than what you may be used to. Gelcoat won't stick either, BTW, that's why they're painted.

    I think marine tex is used on the yamaha hulls for repairs although I'm not sure if it is best to use it on an severe damage
