I have used both the "official" B-Quiet and the HoDepot roofing product like Peel and Seal. �Both seem to work and the latter is cheaper, about half the price per square foot. �After experiencing the ooze problem I simply taped over the joints and exposed edges with metal foil tape. �Keeps the stickum off things it should not be stuckum to.

RE: Peel and Seal for Sound Proofing
A warning.� If you use Peel and Seal under your carpet in the living area
of a Westy at some time in the future you will go to lift up the carpet
and, because of the weight on top from using that surface, you will find
that the carpet is glued to the floor!� Carpet will still come up, with
some effort, to reveal that the Peel and Seal 'stickum' has oozed out and
becomes one awful mess of impossible to get off black, tar like glue.� And
anything you place the carpet on will get it's full share also.� Including
your hands :) (you can get it off of some things with charcoal lighter
fluid).� Ask me how I know....
BTW, I have been very satisfied with the Peel and Seal otherwise and a lot
cheaper than near identical products sold for sound deadening at a higher
price. No smell from day one and no other problems other than as noted
above.
