I wouldn't use the foil backed jute stuff in the doors where there may be a moisture problem. I'm giong to use peel-n-seal everywhere, then the foilbacked stuff on the roof, back of cab and floor/firewall. As for the doors I'll use the bubble stuff over the peel-n-seal. I want this thing to be quiet as possible. I would use 3M spray adhesive, just whatch out for overspray getting everywhere.

Good Luck
George
