Help with a Gel Coat Repair Kit

[cfelton]

Ive done it both ways. If you know your gonna need a couple of layers, I'd do a couple and sand completely down smooth and see if you need any more. I'd always scuff (sand lightly) and wipe with acetone every layer that cured before adding another, if not it'll pop right off. You can tint maybe a 1/4 cup of gelcoat (enough to do all spots needed) and pour off a little and mix with hardener. This way all layers will color match through the repair. I usually wind up with 6-8 coats. You'll notice you'll sand right through the first couple of coats. I try and fix half a dozen spots at the same time so as not to waste the gelcoat I have mixed! Its kinda hard to mix a little tiny bit. I use cheap 1/2 inch brushes from any hardware store to apply the gelcoat. Usually wash them in a cup of acetone and reuse a couple of times before tossing them. Get a box of latex gloves, its hard ta get off your hands. Hope this helps. Good luck!!
