I used the the B-quiet the first go around but they have now become very popular AND very expensive. For the RRC project I bought a bunch of the Noico 80mil and it seems to install just as easily and is just as messy! The B-quiet was twice the price and came in a 50' x 12" roll. The Noico came in box with a dozen sheets of 2' x 3' (folded in half). It's a work out installing it with the roller but the sheets were very easy to work with and cut to fit. In the 110 I installed it on the inside of my doors and on the inside of the outer footwell panel too. But I have a full neoprene sound deadening kit installed over the seat box, tunnel, footwells and lower bulkhead. That does a good job too. But I really should put some in the box in the back too.

Originally the cab side of the bulkhead was lined with a thick sound absorbing, insulation type material (about 10mm thick). It was in such bad shape I pulled it all and installed an 11mm thick closed cell foam material I bought on amazon too. It was much less of a mess to work with then the black bitchimum stuff.
I have a steel roller you can borrow for the job if you like.
