Thats crazy timing, I just finished installing it in the roof of my 70. I didn't use dynamat brand, I used a cheaper brand. Its great stuff, especially if you want your car quiet on the inside. it also holds in heat and cool air better than the old stuff I believe. It's easy to Install, you cut it to the size of the area you want, lay it up to it, pull off more of the backing as you go along. There is a tool just for this that has a handle with a little wheel, it helps you roll it on and get the bubbles out. It's just a sticky backing that holds it on. Its very flexible and easy to use. Just time consuming. The brand I got, they offer in two thicknesses, 50mil, and 80 mil. Its better to use the thicker stuff if you can. I'm putting it every where on my car, doors, floor, firewall, roof...

The only downside is weight. But if your not building an all out race car, who cares? Just ebay dynamat and see what you can find. That stuff isn't cheap though. Hope this helps.

I am contemplating the same thing.  This site tells you everything you need to know, all the brands, price comparison, installation... etc.  It is a long read, but worth it.

I'm using some stuff called eDead...same thing, WAY cheaper. This is for my '76 Cadillac though. Not quite finished with it but the entire cabin and trunk are getting the treatment. I got some stuff that you don't need a heat gun to apply though.

I put some on the inside of my trunk lid to try and make it sound less "clangy"...not much luck for that application

can get it from Best Buy and other stores that install car stereos

I did the entire interior of a 3000GT a couple years ago.   Dramatic difference to say the least.   I wouldn't spend the money on Dynamat, buy one of the cheaper brands like Brown Bread, or that eDead stuff someone mentioned.   In my opinion, they would all be effective.

 Thanks guys, I researched as you suggested. The e-dead stuff seems to be the best value. How many square feet to do an entire car cabin, roof, and trunk area (70 Charger)?  Rick

Sounds good as long as the heat from the roof doesn't affect it. That would ba a bitch if it sagged or fell.

Take a tape measure, and measure from the windshield to the back window and then from door to door.  Multiply those numbers together and you'll have your amount.
