Shop Temps.
Ed, I live in Canada where winter is at times 0 degrees F or colder. My shop is insulated and heated, when I am out there I have the heat on, but I have a 12' x 10' steel corrigated door that isn't insulated. So temperature in the shop is between 40 to 50 degrees F. with very low humidity. I can sand blast steel in the winter and leave the metal open for 3 weeks and it will not rust. In the summer that same steel will be rusty in 20 minutes due to the 90% humidity.
Good mindful eye to catch that. I should have put on a pair of shorts and a Tee shirt for the video.
My suit was at the cleaners.
