Cure for Epoxy Dimpling

Talking with a rep from MAS epoxy at the WoodenBoat Show this morning, I mentioned that the only problem I had was some minor dimpling in the final coat. He said to stir in a small amount of colloidal silica, about one tablespoon to eight ounces of epoxy mix, after the resin and hardener have been mixed together, then let it stand for a minute or two before spreading. This helps the epoxy bond with the previous coat. He asserted that it will still come out perfectly clear and that the small amount of silica won't show when it cures. Haven't tried it, but it sounds like it's worth a shot.

RE: Cure for Epoxy Dimpling

I was at the Wooden Boat Show yesterday and the rep told me to use lacquer thinner to thin the epoxy to rid the boat of the dreaded fish eyes. At this point I don't want to take any chances with the finish, it is looking too good and I would hate to have it get cloudy.
