Hold on given that bit of info, it's in the 70's here but at night 60's. Should I be waiting until later in the season?

hum it may be best to wait a bit then i never do any paint or glass work here until at least late march due to temps.

Depends on how thick you pour it. At about an inch thick it takes about 3 hours to harden but "overnight" to cure. I have worked on material after 4 hours before with no problems.

I'd be willing to bet if your surface was warm enough in the a.m. and you did your work then, you would be fine by 6pm. If you are worried about it just point a halogen at it. That will produce enough heat to keep it stable and keep it from cracking, clouding or becoming brittle. I use an infrared laser temp. gun to check mine periodically through the curing process.

BUT, doing this in the high 70's to mid-80's produces a much stronger pour, mold, etc.........I always use a lamp when temps are lower than what I want.

OK. Let me see if I get one of those hot weekends soon.

What resin did you buy?
 

Joe,
What resin did you get from River Marine for $16/gallon? The only thing I see on there is MAS epoxy resin for $19.95 a QUART and MAS Hardener for $16.95 a PINT. I can't find anything else on their website.:head:

They don't sell the poly stuff online. Slight correction it was 16.95 and container says Fiberglass Coatings Inc.

i buy mine from Parker Boats for $12 a gallon with harder
