You should be able to go to a lowes homedepot etc and get it. I think I used 4 roles to do all for doors the back seat and back wall of my full size dodge pickup. I think I paid around $13 per role but that was a few years back.
I covered this in another thread before but i'll sum it up here. The asphalt based peel n stick membranes are ok to use on horizontal applications as it does get soft in high temps and may even produce running of the black asphalt, I used a Carlisle CCW asphalt based membrane all over my cargo floor which is great because it just sticks down better in heat, but would run in the doors prob. For the doors I used a Grace Butyl based peel n stick membrane that is made for roof applications and with stands higher temps and wont break down and run. I also used EPDM membrane flashing on the doors that is really thick and does not break down in high temps as its made to be exposed on roof decks, but I think its more expensive than a Dynamat membrane. I got a few rolls of the EPDM for free off construction sites I have been to.

I ended up installing the lead I had in the cargo area and I think it made a decent improvement on road noise coming up from back there. Maybe its in my head, but when I removed my spare tire to get the srt exhaust installed I heard more road noise it seemed. I still have a few cans of rubberized undercoating I want to spray under the car and some mineral wool insulation I want to stuff behind the plastic covers at the fenders. And im going to remove the back seat this weekend and lay down a few layers of peel n stick membrane back there.

Right now with all the soundproofing ive done I think most of the road noise is coming from the door seals which I dont know how to make better or tighter, any ideas?

Haha. I know, but I couldnt help just layering everything on, to me more is better. But really the most weight I added was that lead in the back which was im guessing 25-30lbs, that roll of lead was dam heavey. All the peel n stick membrane I used was prob another 30lbs if that, and im just guessing and might be less. Other than that I installed canned spray foam everywhere else which is hardly any weight at all. In my mind I did remove the spare tire so made some weight up there, but then the two srt resinators and pipes added some back.

Re: Lead for Soundproofing..

you'd get the same effect with Mass Load Vinyl and Closed Cell foam with less weight. You may want to add these on top of the Pb if you don't mind the weight.

If road noise persists, I'd use something like Spectrum Sludge from Second Skin on the inside and outside of the cargo area.

Mass loaded vinyl would be the best material probably, I wanted to install it under my hood before but its expensive. All the materials I have installed I got for free off construction sites so it cost me zero. Basically I have all this peel n stick membrane, sheets of lead, and mineral wool insulation so I figured out where I could install them to give me the same effect as car audio marketed soundproofing materials, im cheap. Lol.

And its snowing out here in MA so no work outside on my car for me today, suxxxx.

Re: Lead for Soundproofing..

I don't know if Matt has already directed you here or not, but http://www.sounddeadenershowdown.com has a lot of good reading about deadening, as well as some great products for a great price. If nothing else, you can learn how to effectively use the products you have already.

Informative site, thats where I actually got the idea to use the roll of lead I have in the cargo area. That site says Mass Loaded Vinyl is a cheap alternative to lead, well I already had the lead. Lol. I actually just found 5 more small rolls in my basement cleaning it out, must of been from some previous roof flashing work because it looks used and has some nail holes thru it.
