I am preparing to replace the ladder and stair rails at a rental vacation home in the Florida panhandle beaches . The inground fiberglass pool was installed in 2001 . The powder coating was coming off the ladder and stair rails when I purchased the property in 2005. It looked bad ( coating coming off and slight rusting rust at near water line ) but I want to wait until the was an actual failure . Now a couple of stair treads had broken and the time has come for replacement of both of these items . My question is whether to go back with powder coated stainless vs uncoated stainless steel (more $ and will it last ) or not ? Why was there any rusting ? - Thanks
