I built an Artic Tern last fall. Everything was going great until the second trip out. Some of the glass on the deck started pulling up. Not a big area. I attributed it to a bad batch of epoxy. I cut out the glass and patched it. Then put the boat away from the winter.

A week ago I pulled out the boat to give it a final sanding and a varnish! While sanding I found a bunch of other "wet spots" where the epoxy had not hardened. So out came the 60 grit sand paper, glass and OLD RESIN to "fix" these problem spots. I bought some fast hardener and went to work.

Well to make a long story short, I have 4 large patches with 2 coats of what I think is bad epoxy. And the whole boat with one layer of good epoxy over the patches. But the expoy WILL NOT HARDEN!!!

Now I know people will say I mixed it wrong. But I really do not this that is the case this time. I measured things very precisly. I threw out a bunch of batched that were not measured in the exact proportions.

So what do I do? The boat is now ugly. I can deal with that. But how can I fix it? Should I get out the heat gun and belt sander and remove all the glass? Should I just put a few layers of epoxy over the bad and call it good? Do I just remove the patches, clean things up and start over? What do you think?
