Sound proofing and vibration stopping

I don’t use dynamat in any of my installs instead I use a product called Brown Bread http://www.b-quiet.com/brownbread.html its just as good as Dynamat and all the other overpriced deadeners out there, at a fraction of  the price.

Brown Bread seems to be a superior alternative to Dynamat at a more economical price as well...I only use Brown Bread now, not only because of the price, but because of its superior adhesive qualities...I own black vehicles...3 of them (going on 4, lol...) and I used to have a problem with Dynamatting the roof, because when it got really hot, the Dynamat would fall down and lay on the headliner...I have Brown Bread in my one car for 3 years and it is still up there, without a sag or ripple...
