Really anything, leftovers are fine. Just looking for enough to deaden/seal two doors.
I can't comment on Damplifier Pro as I've never used it. I have a lot of faith in the adhesion of Alpha Damp and Hushmat, but I don't condone doubling up CLD mats. These materials aren't all that heavy, and a single layer at 100% coverage is the most I'd apply. In my own vehicle I haven't used 100% coverage in any areas. Testing has shown greatly diminished returns on reduction of vibrations when you start doubling up damping mats.Hey man how much more deadening ability does alpha damp have over damp pro? I was gonna put two layers of Damp pro on my roof but now I'm wondering if I should go with Alpha Damp.
I have 19 sheets of Alpha Damp and 4-pack Hushmat kits. The Hushmat kits are 4 sq ft.prices?
