Then I thought: "How about that truck box-liner stuff?" It could be sprayed at least 1/4" thick, and is designed for heavy-scuffing outdoor surfaces. I'd spray everything that's usually carpeted, and then use removable plugs for all the drain holes (which were plugged on my car). I would have, in effect, a large plastic dish, 1-2" deep, for the floor. Much easier to drain and dry, presumably just as sound absorbent with removable mats, and decent-looking. After a decent metal preparation, it should seal and stick to the floor as well as any underlay I could put down.
