Ya, I'd say unbelievable too. My Super Nova sat in a wet Boyt canvas gun case for 8 hours in a heated pit with an outside temp of 10 degrees - got home - pulled her out - said "Crap! I need to get a waterproof gun case". Dried her off and wiped her down. Residue but no sign of rust in or on the blued barrel.
Ya, I'd say unbelievable ... Interesting first post.
