I thought that i remembered reading that there is a 3M product designed to match white gelcoat that you can use for filling so you dont have to gelcoat after you fill holes?

i have to fill some holes from my old hatches and also from removing the life line on the deck

Anyone know what im talking about?

Possibly Marine Tex? It comes in Gray or White, not sure if it's made by 3M though...

eh whatever i will probably just fill them and gelcoat over it, at the very least it will force me to wetsand my deck. i know i will be dragging my feet on that project
