What is the best material? B-quiet, Phatmat or Dynamat?
Any experiences with these dampeners?

I like the dynamat extreme, it works well (I have used various regular, which was *** but the only thing avail back in the day as well as super which work pretty good). I dont like b-quiet, and I have not used Phatmat. If you dont mind spending a little more and can find it try using some aerospace damping it works amazing and is a lot lighter.

Dynamat is WAAAAY over priced.

I'd say B-Quiet ultimate (most of my competition vehicle is covered in it) ... otherwise I'd give Second skin Damplifier a try

Over priced, probably, but it worked better for me than almost everything else I have tried (except for the aerospace stuff that I tested , which is way lighter and dampens a lot better as well), plus extreme wasn't a mess when putting it on. Although, I have never tried Second skin Damplifier or Phatmat.

I have only used B-Quiet extreme so far and I have no complaints with it - yet.
