I just received my purchase of some Noico 80 mil.
https://www.amazon.com/Noico-deadeni...deadener&psc=1I work with a fellow who has installed sound deadening material in the car audio world for many years primarily using dynamat. He was thoroughly impressed with this stuff just by handling the product and for a fraction the cost compared to the "brand name" stuff I'm happy already with my purchase. I will post again once installed for further input.
