Add me to the list... used peel-n-seal on entire cab. Also used double side aluminum bubble insulation as well, I found that it worked better on cab ceiling because it was not as thick and the new headliner is a b*@#h to install. I did not use bubble insul. on floor, instead used jute/Aluminum insulation glued to an outdoor carpet cut to size. (I did not want to glue directly to the floor).
Bought it all at Home Depot.
No smell ever....remember to seal any holes on firewall or floor and you'll have a much quieter and cooler/warmer cab.
