Molded Vinyl/Rubber Flooring Options?

[PokinatchaPunk]

So I'm in the process of revamping my 2g and have all of the internals pulled out. That said, I'd like to replace the old dirty carpet but dont want carpet. I live near the beach and hate the never ending battle against sand in the carpet. If I have a rubber or vinyl floor, it'd be a lot easier. I've searched all over but can seem to find any molded sets that aren't carpet.

Any one have any experience using rubberized undercoating spray over sound deadening pads/rolls (I don't want to just spray everything...i.e. wires)
