20200 Silencer Megabond Door/Hoodliner Kit - (2) 23" x 36" Sheets - 1/4in Thick 11.5 SqFt.

Installs relatively easily. Grips very well so it's best used with patterns for precise fit the first time. Only drawback, and it's the big one....cost! You can get the same product much cheaper elsewhere. Look on the internet for Super Soundproofing Co.

I used this on my cars firewall. It was easy to put on and looks like a factory product.
