It's not a spray...but check out Cool-It Mat Insulation . I've used it with great success.

Duke, look http://cw-diesel.com/dbwsoundproof.htm and see what I did to my F-350. It did make a difference. I have not check into the latest materials that B-Quiet offers, but the brown bread did work quite well, especially considering the cost. Most of the spray on stuff was much more, at least what I had found.
