I live on the coast and my shop is un heated and uninsulated. I was talking to a guy who rebuilt machine tools for a living for most of his life. He was the one who told me about Fluid Film. Goofy name, goofy dated looking can, not cheap, but totally amazing stuff! Best of all it's completely non toxic and seems to last forever. And it's available at auto parts stores. It has completely stopped all the rust on all my machines and one can goes a long way. I told my neighbor who has a fishing boat that fishes off the coast here and it's stopped all his rust.
