I'm not sure how well it will work in extreme cold weather , but I use BREAK-FREE, a gun lubricant on everything that sticks and squeaks here in NC with great results. I think it is silicone based , not exactly sure but it does put a protective coat on metal and will stop your guns from rusting.
Have used PB Blaster too from manifold bolts to car locks. It will penatrate well but I don't think it has anything to protect the metal in it..
I have used Coke to tenderize a cheap steak, but I prefer a 2 beer marinade...One for the steak, one for me....
