Wanting to do some deadener while the body is tripped down but cant make up my mind on good quality buytl product. I know D-mat extreme is good but way over priced then Damplifier pro gets great reviews Audio technix is sold out of 80mil for about two months and Fatmat mega is priced right but gets mixed reviews i think mostly because guys confuse it with the orginal asphalt type. Whats the go to for guys here on the forum please no peel and seal comments only good Butyl deadeners.
