Here is one caution: Propane and kerosene produce prodigious amounts of water vapor as a byproduct of combustion. I used a 60K btu heater in my cold garage one time. The very next day everything iron or steel was coated with the cutest layer of rust. I mean EVERYTHING. Think what that water vapor would do to your epoxy curing. The fix to this problem is to use something that is vented to the outside.

I am at the "just about to start glassing" phase on my Great Auk
: and the weather here in Portland (OR, not ME) has been diving down to the
: 40's at night. I need to try and keep things above 60 degrees for my West
: system Epoxy (105 resin with 207-SC hardener). I tried using a 1500 watt
: electric heater (about 5600 btu), but it only raised the temp by a few
: degrees. I looked at portable propane heaters, but they seem to suck a
: huge amout of fuel (10-12 hours on a 20 lb. tank). There are portable
: kerosene heaters for about $100, but I have no experience with them. I
: also thought of possibly using a couple of 1000W halogen worklights to
: generate some heat. The space I am dealing with is a two-car, uninsulated,
: attached garage. Any wisdom would be appreciated.
