i was looking at the dynamat door damper ,it looks like modified water and ice shield used on roofs which is alot cheaper ,it is not as thick but at the price double it up ,your wallet will love you !
everybody knows this, but there are diffs. dynamat sticks much better (I've used both, I am 100% sure of this) and it doesnt' carry that tar smell roofing stuff does.
