YouTube - EXO Peel And Seal Review - Cheap Car Audio Alternative To Dynamat Sound Deadener
and i have a video of my own, a pepsi can 25% covered with sds and one with 25% coverage with peel and seal from my local lowes. dropped from 10 feet, 3 drops and read with a dosimeter. the peel and seal was 1.77% with a standard dev of .07% less effective. and it cost 1/9th the price of sds. so you are paying approximately 85% too much for sds. granite this is just a can, and their samples they sent me, and not a complete car, but i think the tests are good enough to show the sds was nothing special and highly overpriced....
edead on the other hand does not have samples that i know of. therefore i cannot do this test. therefore i was looking for your guys opinions reviews on it. but seems i get everything but that on this site....
