Not if you need them in a hurry! lol
Damn, I need to get a safe... and get on the SBR bandwagon. <sigh>
In order to rust, steel needs moisture, oxygen, and dissolved salts. The lack of any one of those means the speed of the rusting is greatly decreased.
Did you see the thing where they pulled the German-marked T34 from a swamp recently? It was in amazing condition, and it had been submerged for quite some time.
What kind of finish did it have?
In Soviet Russia, steel finishes you.
put a dehumidifier or a big golden rod down there or it will never stop. just coating it with something like that won't help much. I'd prime it with that automotive stuff that turns rust into primer, then coat it with a good enamel.
You could run into serious problems unless you blast before coating with a polyurea. I'd just remove the rust, solvent wipe the entire inside and coat with an epoxy. Cheaper too.
I wont! I'll hop the darn fence in get in my landladys storm shelter!
If it's soil side corrosion, it won't help and would be a waste of money. Contrary to what some of the idiots here would tell you, soil side corrosion is an issue, and it's compounded by the unbelievably $hitty job some of these fly-by-night storm shelter manufacturers do preparing and coating the exterior of their steel shelters. If it's soil side, do what you can to prolong the life, by grinding, patching & painting, but understand, you're fighting a losing battle & the shelter will have to be replaced at some point.
If the corrosion is inside then wire wheel it, put a primer that contains corrosion inhibitor on it, and paint to match.
