I got 50 feet of b-stock for 100$, shipped. That's 2$/ft^2, SHIPPED! I am waiting to try it out. I thought door deadening took more like 10-15 ft^2 per door, especially with a layer on the outer panel and a layer on the inner panel (but I have never done it before, just what I have heard.) Or do you not have do deaden both panels? If 50 square feet could do my doors and at least part of my parcel shelf I would be ecstatic. Oh and for what it's worth, I have heard asphalt products are disgusting and will smell and have smelled the nastiness from peal-n-seal in a nice car and I would definitely never put the stuff in my car.
