Building on Gordon’s theme, when I rebuilt the bay floors under the AC units, I added a fiberglass bathtub floor. I used fiberglass cloth and epoxy to make a protective cover for the steel floor. I spent some time in the composites industry and this is the same technique that would be used to waterproof a wooden strip canoe. If you go this way, a 3 wide paint roller handle, no roller, is a fantastic tool for spreading the resin and smoothing the cloth.
