My neighbor had a house fire Sunday afternoon which was contained to the basement. The only place structural damage is visible is the basement and the upstairs has a lot of smoke damage. He has a fireproof gun safe in the basement so he thought he was ok but when he opened it yesterday, the day after the fire his guns inside were all rusted. It didn't sound like anything was melted inside the safe. He said that the gasket did not swell to seal the safe. I've been thinking about buying one of these for a while. Has anyone had any experiences? Thanks for your input.
