Here's an interesting link I found for soundproofing material called
QuietCar:

http://www.quietcar.net

(Don't forget to watch the video... great marketing hype!)

I really know anything about it accept I'm going to look more into it. They
didn't make it easy to find, but I did locate some technical information
about it here:

http://www.quietsolution.com/html/technical_docs.html

From the looks of it, there is also a "QuietAir" product, but I couldn't
really see any difference between that and QuietCar in the tech docs --
price is the same.

They sell a "special" air-powered spray gun to apply, but also note it can
be applied using a brush or roller.

Weight is about 12.5 lbs per gallon.
