So this past weekend I was removing some old wiring from my brother's Jeep, which I used to own. While I was in there, we installed new speakers in his doors (more info here--- http://www.caraudio.com/forum/showthread.php?t=202338).
Anyway, back in 2001 I installed some sound deadening in the doors and front floorboards of the Jeep. It was a DISASTER. I used the Basic B-Quiet, after guys on the Jeep forums (hey, it was 2001) recommended it over Dynomat for cost and value.
Anyway, it was installed in moderate temps, was applied with a roller, and was heat-gunned in place. I did the outer door skin, the inner side of the inner door skin, and the "middle" side of the inner door skin, as well as the floor. The floor was fine, but the door skins- particularly the outer skin and "middle" skin all were a mess. The deadener had slid down and formed a puddle on the bottom of the door, and the adhesive was all over the bottom of the door and the inner and outer surfaces of the windows. It made such a mess that it took hours to clean up, just to clean off the windows and to get the drains at the bottom of the doors cleared out.
Fast forward to this past weekend when we did new door speakers. Not only was most of the deadening still there (particularly the inner door skin), it was SOLIDLY attached to the metal surfaces. The doors were still deadened, and it looks like after that initial fialure, the adhesive held tight and did its job.
I kind of wanted to share that long-term performance report, since I was sure it would ALL be in a puddle in the door all over again.
So here is the real question: I am about to deaden my new car- is there any way to get the doors to to the point where the stuff sticks and STAYS, rather then to do what happened with the Jeep?
