that's what I was wondering as I read.

The potential downside that I see is that being on the outside, if this thing encounters wet conditions, water trapped between the sound/deadening/mat and metal could cause rust issues. I would think that stripping everything from under the vehicle (pull transmission, brake lines, etc..., and spraying with a heavy coat of rhino-liner type material may be better than adhesive backed sheets, but that sounds like a ton of work, and may still cause problems down the road.
