(LINE-X) Has anyone used this product?

[40_Tudor]

I was surfing around the other day looking for something to spray on, or have sprayed on, my new floor in my 40 for insulation, sound suppression and to limit rust. I was thinking maybe Ryno or one of the others and ran across a product called LINE-X. Supposed to be a two part spray on liner like Ryno but stronger. It's used on truck beds, floors, foundations and lots of other stuff.
Has anyone used this on a streetrod or truck bed and does it hold up like its advertised?
