Old Yaker - I'm in the same boat as you. Every time I plan to start mixing epoxy the temps dip below zero. We're building in my basement, and temps down there have been around 45 degrees. I'm thinking that I might be able to rig up a lightbulb under a coffee can and place the epoxy bottle on top to warm it. I bought the slow hardener, so low temps are going to really affect me.
