: good advice. Current Designs sent gelcoat for the kayak. Is gelcoat
: a effective covering for the hole edge or is NAPA resin
: preferred ?
: There are several holes ahead so I can try the advice to see what
: works. Carbide sounds fool proof.

The gelcoat is there to make the boat pretty and resist UV, the laminate itself is waterproof. The only thing you need for installing a bilge pump thru hull is a sealant so it doesn't leak, I prefer Lexel.
