Deck Drain Frustrations!

Why is it no job is ever as simple as it seems...

You may already be planning this, but the rule of thumb in filling holes is to grind back and glass over an area in a 12:1 ratio to your hull thickness - if your hull is 1" thick, then grind back a 12" diameter surface, and feather it for how many layers of glass you plan to use.

Granted you are really only reducing the diameter of your hole vs permanently covering it. You might want to use a few layers of glass over it & feather out some where the 1st layer or two is bonding to straight fiberglass, not gelcoat. What did you use to thicken the epoxy?
