Also, Dynamat is not meant to be sound-deadening material. Its sole purpose is to add mass to whatever it is applied to, making it heavier and therefore less prone to rattling or vibration from acoustics. IMO, you can find better material to use.

According to a Dynamat promo, dynamat does reduce sound but not by adding mass but by changing sound energy into heat .. The amount of heat is very small but this is how Dyamat is able to quiet sound with a very lightweight product.. I bet you could do the entire car with less than one hundred pounds of Dynamat..
