I found boat deck hinges that claimed to be all stainless. Overkill probably and they were pricey but no evidence of rust. My door hinges were regular HD cabinet hinges and the ones near the overspray from my sump rusted beyond repair in about a year. I guess I'd do the SS. At least it should last longer and if the pin rusts you won't have oxidized copper flakes getting I the tank. I wouldn't want unstable copper "over" the tank
