Make a box about 2 1/2 feet square out of foam insulation board. Tape it together with duct tape. Leave the top loose. Run a wire inside through a hole about halfway up the side and attach a light socket with a small 15-watt bulb inside. Now you have a warm box to keep your epoxy in during the winter months. The epoxy will flow easier and set faster. Use this also for paint — warm paint flows on better.
