Generic asphalt based stuff from Home Depot that is designed for roofs. Costs $16.99 a roll, and each roll weighs roughly 4lbs. So far I've used 3 rolls in the area you see in the picture (incl. the opposite side). In the high resonance areas I double up, everywhere else is single layer. Bang around with a rubber mallet to help id noisy areas.

This is the second vehicle I've used this stuff on, and I can promise you if it is applied in hot weather, or heat each piece and it's installation location with a heat-gun or 1500W hairdrier (very time consuming but essential) and take your time to thoroughly hand press the entire area of each piece once installed, it will never loosen or fall off. Matter of fact, it is a ball-buster trying to remove the stuff so plan wisely before applying.

As far as asphalt smell, after a day or so it is completely undetectable. Did my doors a couple of weeks ago (2.5 rolls), and two days later the car had been sitting all day in 97 degree Gainesville heat, yet when I got in the car there was absolutely zero smell. Oh, now the car sounds like a tank when closing the doors. Very noticeable in parking lots as the rattle free solid thump sounds high quality.

The bottom line is this process is extremely time consuming when done correctly. But the sound reduction and even squeak/rattle reduction is priceless.

interesting. I was able to get a 4-5 sheets of eastwood (dynamat) for free through work, which was enough to do my doors and a little more but not much else. I was looking for something like this

 

thats the stuff - I did a mustang a while back and absolutely loved it. I also have 6 rolls in my garage waiting to go in my TA. I could smell the adhesive for less than a day and sitting out in 104+deg TX heat, it never once smelled or got gooey like some of the name brand sound deadener.

 

How do you like the nice solid thump you get when closing your doors?

 

havent finished it yet ill let you know tonight haha

 

Looked for this stuff this morning and didn't see any. Will try a different store.

 

I can only find it at The Home Depot. It is generally in the back of the Roofing section. They only seem to stock 6-12 rolls, so it is easy to miss when looking for it.

 

I've seen it at the nearby Lowes, but not Home Depot. The brand at Lowes is Peal-N-Seal.

 

Going back out today to look for some. I want to do the rear of the car. _

 

Peal-N-Seal is not the same - I have no personal experience but supposedly it will ooze everywhere and smell when you car gets hot

 

I have experience and can say that it doesn't happen. My trunk looks like CPO's and its fine. Then again, I live in MA so I can't vouch for TX/AZ heat. I've only seen 1 thread where someone mentioned a smell and he is in Houston. I've also heard of some other sound deadeners having a scent too so YMMV.

When I laid down the Peal-N-Seal, I also sealed all seams and edges with aluminum tape to make sure I end up with a continuous surface and all edges are secured to the panels.

I also have some Frost King duct insulation on the hump behind the rear seats.

 

wow sounds great, i think i'll get some of this stuff

 

Since we are comparing, has anyone seen if either the Home Depot or Lowes version is any thicker?

 

interesting

 

Sticky worthy imo.


Going to have to do this before I get a stealth box and sub.

 

x2 on all of this. Was semi hesitant doing it on my wife's car and just went for it. Applied with a heat gun heating the piece and the area it was to be placed than on the back pressing it with a roller and that stuff isn't going anywhere. Have been driving the car the past two months with the stuff in it and even sitting out in the sun I get absolutely no odor.

As for thickness I did notice through some research it is thinner than the typical dynomat extreme. Double layering it would give the same thickness but one layer over the entire thing was ample enough.

 

I haven't done my doors yet but for those that did, did you reach inside the door and apply it to the fiberglass skin or just the inner area where the interior door panel touches?

TIA

 

I laid mine on the fiberglass skin too.

 

I didn't think of that, just covered the inner door panel.

 

There's 21 of these bad boys in stock locally. On the door panels, did you take off the insulation on the back of the door panel? I'm guessing so just thought I'd make sure.
