[quote=loquinho][quote=traphappy]Resin does not form a good physical bond to old fiberglass and is subject to easily peeling off. I'd consider doing the outside repair using west system epoxy and glass applied to a clean surface. A $20 pack of G-Flex would be adequate.[/quote]
I sanded down the gelcoat to raw fiberglass and used layers of fiberglass mat and totalboat two-part epoxy resin.[/quote]
