Best sound dampening material
 

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 ass 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.

extreme dynamat saved my trunk!

extreme dynamat FTW

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.
