I heard several guys like this product for various areas of the cab. I just picked some up (6"x25') and thought it would be thicker. Can it be doubled up? 2 or more layers? I'm thinking of doing the roof, inner doors, behind the seat and under the dash/cowl not covered by the floormat and firewall dash pad. Any suggestions?
