Thank you! It’s definitely not climate controlled, but the soundproofing foam on the roof and door and the airgap between the OSB lining and the outer cladding do help somewhat. A small oil-filled rad duing the worst of winter is handy as well, but yeah, rust is something that crops up a fair amount. Scotchbrite, wax on the lathe and bandsaw beds, and I keep a candle stub in my pocket and every time I use a handplane the sole gets some wax. That helps, but nothing really ever stops it.
