The second skin Damplifier Pro is some really awesome stuff. The adhesion is second-to-none and the foil backing is very thick. Apparently testing has shown it works well from an acoustic standpoint too.

I also used their Heat Wave product in crucial firewall and toe-board areas, could not be happier with the improvement that made.

I am all for saving money where you can, but I think this may be an example of getting what you pay for. Especially in the roof and door panel areas where you have to demand that the product stick forever!
