: 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?

It sounds to me like you might not of stirred the epoxy enough. I had one batch not set up only in certain spots. From then on I made sure that the epoxy was stirred very well and didn't have any more problems. The people at pygmy advised me to remove all of the uncured epoxy (a cabinet scraper worked good) and scrub ( the pads made by 3M did a good job) the area good with laquer thinner, then reapply epoxy and fiberglass. I was fortunate that I learned this while glassing the inside of the hull. It would probably be best to talk to someone at Pygmy. Good luck.
