I have been working on the Laker 13 and I've hit a snag. Irecently purchased marine epoxy from D.W. and the second coat of glass has not cured yet. The problem is that it has been 12 days! I miwed the resin and hardener according to their instructions and the project is in my garage which I have been heating. I'm really at a loss here and need advice BAD.

You say that your second coat hasn't cured yet, did the first coat cure with out problem before you applied your second coat?

What brand of epoxy are you using?
What mix ratio?
Not curing all over or just in areas?
Did the stuff left in your mix cup cure? ( I like to keep those available to use as a bench mark)

If your first coat cured like it should have before you applied the second coat, and the second coat hasn't cured, I would suspect a mix up of ratios on your part. Maybe went with a 5:1 when you wanted a 2:1 or you lost count and just went with more resin.

Mix up another small batch and spread it on some scrap wood and see if that cures. If it does, your mix was off. I think then you would have to remove as much of the un-cured stuff (paint scraper) as possible. I think then applying another coat (properly mixed) over top would work, may have to give it some extra time to get a good cure. That is just what I think would happen, a second & third opinion is really needed.
Wouldn't hurt to run that by the epoxy manufacturer, and go with what they say.

Good luck.

Excellent questions Dangermouse. Also you posted earlier about staining.Did you stain and if so did you use a waterbased stain. Is the glass soft or does it have a thin film on surface. Could be a heavy amine blush on surface. WE need some more info please

oh oh... that doesn't sound good. You might this in a small test area:

Brush some hardener only on it. See if that does anything. You could try warming up the but if it's been 12 days, you might have to scrape it off.

Thanks guys. I used the recommended 2:1 ratio from the manufacturer. It's just called marine epoxy, and I believe it is from a 3rd party in Florida. The past 3 weeks here the weather has been all over the place, from snowing one day to 70 degrees the next, to rain. I decided today after I got home to remove this uncured coat. What do i do next?

Never heard of anything like this before.
I'm not trying to be an alarmist or pessimist, but if the manufacturer doesn't have a "cure" that can be applied, I'd be tempted to scrap what I've got and start over.
My only concern is for safety down the road when my rear-end was paddling that thing in the middle of some lake or river.
For what you've got in it so far, it might be less work, and frustration to start over. Chaulk it up to Murphy and the learning curve.

I had a similar problem on the interior of my first boat. I somehow screwed up the ratios. It is a MESS to get the old stuff off. But then, restart just like it never happened.

I'd maybe get a different brand of epoxy?

Tarheel;
Whats the latest on your epoxy problem? Did it cure or was it a "do over"?
