Rear door vibrations
When i put my new subs in, my rear passergen's door started to give out alot of vibrations, i solved the problem,(which eventually happened to both doors, heres what you can do if your at a lost for finding that one thing that may be casuing vibrations in you rear doors
first. remove the door pannel
second. pull this black stuff back(it might be really hard at first, so pull gently but it will eventually come off, o and it sticks right back on

thrid look for these two bolts

bolt one

bolt 2 is behind that piece of plastic, the picture wont up load so untill now this is the best way i can describe it
for some reson these will tend to get lose, not by much, but just enough to casue alot of annyoing vibrations

Looks like great stuff to use to fill airspace and solve rattles.
Sorry, couldn't help myself.

Yea alot of people use crazy things for deadening. Concrete is the SPL cars or people who dont care bout there doors and wanna be a sick *snip* daily driver that can hit on the meter.
I mean people use roofing material for sound deadener also.
peel n seal ftw
*EDIT by swartlkk* - again with the language...
One of the links that has been posted on here comparing different deadening materials actually tested out roofing materials. From what I remember it didn't do too bad comparitive to it's price VS peel and stick made for automotive use and it's price.
