anyone who has used dynamat or hushmat knows that the stuff is way overpriced,i did a compaison test with both of these to tite seal flashing material (you can get it at home depot)this stuff works just as well and costs about a fifth of what the proud guys get.it is a tar based self adhesive roll with aluminum sheeting bonded to it about 1/16" thick.once you stick it it is there for good.used it before and it kills the road noise just like the million doller stuff.if your a salesman for dynamat , sorry
