Now you're thinkin!

With your cold temperatures, I'd still go with Fast Cure if not the Cold Cure; even with heat lamps and blankets, Slow Cure or No Blush will still take many days to cure.

The "Heat Tunnel" sounds like a good idea. Another great way to heat the hull for glassing is to suspend 100 watt light bulbs inside the hull. The only way heat will escape is through the hull, and that will in turn heat the epoxy. The tarp on the outside is still a good idea; heat loss is a function of the difference between temp. inside and temp outside-if you have no heat outside the boat, the light bulbs inside the boat won't heat your boat as efficiently.

To control outgassing, I'd put a bunch of lamps inside the hull a few hours before glassing ( 5 or 6 bulbs ). After glassing, take 2 or 3 bulbs out, so you still have heat, but you're not increasing the temperature which causes the outgassing.

I'd skip the fan--you'll just kick up dust that you'll end up having to sand later. Put the heaters right underneath the boat--where they're most effective.

If you have the space and the inclination, you could suspend the tarps from a temporary frame. When you're done working in the "heat tunnel" just lower the frame (with rope/pulley system maybe?) to a foot or so above the boat. Less space==heated more efficiently (hey, here's an equation I'm good at!)

You're right--not too much heat will be needed to get 'er up to 50*.

Good luck, Shawn
