How did you deaden the doors? I assume that you used B-Quiet? Did you use other material?

The cheapest material out there, eDead_45, was not near as effective (if much at all...), the glue was not 'permanent', very minimum mass. It was too thin. But it was extremely clean and easy to apply, and being super cheap, I used it for double and triple layers in the trunk and under the rear seats (large horizontal surfaces).
