Re: Attaching StarBoard to gel coat and fiberglass
Having done this just recently with my hatches and windlass the only way to get a good seal is to mechanically attach the Starboard with screws or bolts.
Any good bedding compound or butyl will work but it will not adhere the Starboard to the gelcoat.
Sand the gelcoat surface and clean the Starboard with alcohol before applying.
