: Thank you all for this insight. I was not thinking I would
: encounter explosion force distruction, but rather end up passed
: out on the floor. No stranger to this, but I digress to my
: college days. I am a bit more healthy these days. The propane
: option is my best option I can think of becasue I have one, and
: it seems to put off about as much heat as I would need to
: accomplish this task. I am not looking to invest in other
: heating options. I just was not sure what health risk it would
: present. I have a clean shop with no other flamable or toxic
: variables. So It sounds like so far this would be a reasonable
: option to pursue. And yest I will have a CO detector in the
: area.

It depends on what kind of hardener you are using, as well. I stupidly tried to use some of the slow Raka hardener I had in a 60 degree shop and it took a day to harden. I bought some fast hardener and it successfully set up in a fifty-something degree shop in a matter of hours. They also have a "low-temperature" hardener for even colder temperatures than that. I'll also be trying to glass the inside of my deck this weekend... temps will be in the fifties at best. Just trying to get done before winter...
