Not sure about this stuff, because I am waiting on others to continue to prove it out. However, the Kilamat did help (dynamat Amazon knock off) and putting 3M tape on that stuff is very hard to remove, but 3m tape on fiberglass peels right off.

I'm thinking you have better adhesion if you already have dynamat down and then use this over top. Again, $50 went a long way on the kilamat also
