I’ve used POR15, but only on smaller areas. Similar products will probably help, but they’re going to be a stop gap. I hope the tank isn’t hanging off that.

I know K won’t like it, but I’d go to the local wrecker and look for any large floor panel that might be adaptable. If the edges are good you might be able to trim it out and replace it with something close. The oem floor mat will hide a lot and it wouldn’t be an irreversible fix. But safe in the long run.
