No... unfortunately this isn't a qualitative comparison... I'm hoping you guys can supply that...
With all this talk of sound dampening lately I decided to do some research into various brands. This is the data I have concerning various brands I've come across.
I figure its helpful to have it all in one place. I hope it helps some of you out there figure out what you want to get.
Please post any feedback you have with any particular brands (especially comparative experiences).

Numbers and data are all taken from the respective brands' websites, so you may want to take that into consideration when viewing the data. Some websites had errors or conflicting information so I put a ? next to the data that was questionable. I also have some ? on areas I was not able to find the corresponding information.

Products were arranged in descending order of price. Edit: Prices do not include shipping or special scionlife discounts from sponsors.

its in a pic b/c it wouldn't post with the proper alignment. Hopefully if/when that gets fixed I can just post the text:

Couple things on eDead.

v1 and SE are asphalt and rubber butyl, not just asphalt

v3 is a kind of latex

Use SCLifeB at the checkout and you'll get it.

yeah it was a really hard finding out info on edead. I only put up the info that I found... I 'm sure there are many materials there that they don't mention. though the mats having butyl is a pretty safe assumption... I'll go change it so it doesn't look like we'd be putting road in our cars...

Didn't post the composition of the liquids... no one was giving that info away.

I knew about the discount.. which is why I added the note about not reflecting scion life discounts... I figured someone would post it anyhow.

I have never paid for sound deadening products in my life, but I have used it all. When I started work on my TC, I got a bulk pack of Dynamatt Extreme. I was also sent a bulk pack of HushMatt . I have to tell you that in my opinion the Hushmatt is a better product. Nothing installs as effortlessly, and adheres as well (without surface treatment). HushMatt cost more due to the greater investment in the material and best of all...no foil cuts!
I have both the Hushmatt product and the Dynamatt in my car. I used the HushMatt on all of the verticle surfaces because I didn't want to "waste" it's great capabilities on the floor. Gravity helps anything stick there!

Oooo..ouch... dynamat

Ive nevered tried Hush Matt but Dyanmat works well for me. Holding up so far.

i've only used dynamat products... so i can't comment on the other brands, i woould expect them to work similarly though...

extreme is pretty light, take your time on the installation and you won't get cut much
regular dynamat is really inexpensive now... but requires a heat gun and cleaning the surface... more work to apply...

I've also used the rockford stuff.. it's similar to the reg dynamat, also inexpensive...

Chimmy3

hey guys also, one issue I've noticed that I wanted feedback on was that some people talked about the asphalt heating up and smelling on hot days.
I was wondering if anyone knew whether this truly was a concern or not?

That is one of the main reasons I included the claim "odorless" if the product claimed it was so.

Has anyone ever come across this problem? and if so which products caused it? or is this really not a problem and its all just clever marketing ploys?

I highly recommend Dynamat Extreme. Easy to use and very effective. I always suggest staying clear of cheap asphalt based deadners as most will emit an odor in time and also weigh quite a bit more. If your on a budget, use the better deadners on the doors and firewall area and on any complicated, irregular areas. Good luck.

I'm too tired to comment on any of the posts really, I've learned if people think a certain way, there just really isn't any reason to push/argue about it, however, I will comment on chimmys question.

eDead v3, as stated emits no odors after drying(while wet though, i think it smells like mangos, but this is my opinion). the v1 and v1 SE haven't emitted any odors, and they were in the car all summer long, in texas.

DenZinz

stay away from standard dynamat or any alike. they smell, hard to work with, and dry up in time. Go extreme or sometime compairable.

superfreestyle

Well now that i know what the discount code is maybe someone can tell me the company and web address that gives this discount

Chimmy3

elemental design makes edead...
their web site is www.edesignaudio.com
you'll also see their banner on the forum page and sometimes up top

Max2k

So, should 2 gallons of liquid edead be enough for my xB?

kaosmoon

certainly will be.

You can get it in black too here as well if blue doesn't float your boat ; http://www.icixsound.com/vb/auction.php?do=list&cat=6

Max2k

So that'll cover everything (floor, roof, doors, pillars, etc)?

Thanks for the heads up on the black, but I'm going to go with the blue because of the scionlife discount.

failed_ethics

For me, 1.75 gallons did the doors(inside and out), all the door panels, the rear hatch floor, the rear fenders, and all the interior panels and pillars.

But I applied THICK layers, so you shouldn't have a problem doing your whole car with 2 gallons.

Someone please make this a sticky!
