Good tip on the peel-n-seal. Sounds like a winner. I used one of the commercial-made firewall pads (rubber face, and heavy felt backing). It's good, but I probably coulda used something cheaper. I used the foil-faced heavy felt deadener on the rear of the cab and under the seat, the floor, and on the toe-board. It's kinda pricey too after you buy a good 3M spray adhesive and foil tape. I'm gonna try the peel-n-seal on the roof.
