Dynamat question

[Spartan]

I was doing some looking around at prices on this sound deadening material.  Sinse my car is not in my garage (I can't get it here till I get the interior back together and the brakes fixed since one of the rears locked up on me) I don't have it close to do any measuring.  I noticed Dynamat has a bunch of different products as well.  1st question is what is the best type to use in our Chargers (mine is a 69).  Question #2 is what do I use this on? (I know the floors but what about the roof, behind the rear seat and how far up the firewall area do you go).  3rd question is how much do I need to do the car? 4th and finally, if I do the floor, do I need to put extra padding down over it before I put the new carpet down (and do any of you guys have any pics?)?

Sorry for so many questions but I am going to tackle a bunch of this myself to save money and if I can get all my materials I need I will hammer this out and get my baby home.

Thanks,

Sparty

You can use this http://www.accmats.com/products/Sound/sound.htm   all of the asphalt based soung deadeners are kind of similar but Dynamat has some specific materials for certain locations in the vehicle, some of the members have used the bubble foil type of insulation in there floor, roof and doors that you can get from home depot, I'm at that point now, if you install the asphalt stuff on the floor put it on the metal first then the foill or jute padding then carpet, the doors and roof maybe just the foil stuff.

I'm sure someone else that's already done it will let you know what they did and give you there opinion.

Personally, I went with Elemental Designs' eDead - http://edesignaudio.com/category.php?type=damp
From full interior strip, I started by silicone sealing in all plugs in the floorboard to ensure that water wouldn't get under the mat and rust out my pans.   I then layed down two full layers of v1 SE (the thick stuff) in the easy-to-get-to interior portions.   I then used the normal v1 for the more difficult areas, and areas where thickness mattered (like underneath the door panels).   I then coated it all with a thin layer of v3 painted on to water-seal from the top.   I also painted in v3 very thick in places I couldn't get to easily, including a thick layer on the inside of the dash framework. I did the same on the trunk.   The v3 is available in black (though it's actually more of a dark, dull grey), so it doesn't look too bad where it is visible in parts of the trunk.

Altogether I used 2 cans of v3, 100 sq ft of v1se, 40 of v1.   The interior of this car...   When you close the door, it sounds like a rumbly-engined lexus   It's really nice.   Road noise is nearly gone, comparatively.   Spots I payed closest attention to were the firewall, rear fender wells, inner dash frame, rear deck, doors, and entire trunk area.  

Of course, mine is something of an extreme route, you could easily go with less

Good stuff here. Can anyone comment a little more about the "like" material that can be purchased at Home Depot. Exactly what would I look for, anyone have a stock number?

Huge thanks!
