I don’t keep my shop heated when I’m not using it, which can lead to some frustrating material losses. After throwing away many containers of glue, caulk, latex paint and water-based urethane varnish because they froze in my shop, I finally got smart. Now when winter sets in, I put any supplies that are subject to freezing in an inexpensive foam cooler that includes a 4-watt light bulb on an extension cord. It costs about a penny a day to run the bulb, and it puts out barely enough heat to keep the contents above freezing. But that’s all I want, and I can sleep knowing that I don’t have a fire hazard on my hands.
