Well not really specs persay..... But you get the point. It was only $90 after taxes and shizz. Its better than nothing. After I get my Maw-15's and stuff I will make a build log......

Being asphalt based, you might not get adhesion as good as butyl-based products. And it might smell after installation. But YMMV.

I spent 1/2 hour arguing with the jlcaudio guy sounddestroyer mat, swears its butyl, so he sends me a sample swearing its butyl, yup butyl my ass, my butyl rubberized apshalt, I could smell the asphalt as soon as I opened the envelope. Although for 80 $ for a 100 sqft It'll prob do the job prettty good. and inall honesty I haven't had any problms with the beter quaility rubberized asphalt mats, especially for that price, and I live in Fl. Good luck with your project...

If it does leave an odor.... would there be anyway to cover the smell?

Time. In the future Secondskin or Raamat are really nice choices.

I've got Brown Bread in my car. No adhesion problems at all. No smell either. Did get some tar runoff in the spare tire well from the 120 degree summers here in Vegas though. Nothing that shows.

Ant from Second Skin sent over some Sludge a while back....that stuff is sweet.

You can tell pretty quickly if it is asphalt or butyl by dropping a small piece in an ounce or two of mineral spirits. Wait 15-20 minutes. Asphalt will dissolve and turn the liquid brown. Butyl will either do nothing or break apart into black particles. If you aren't that patient, take a Bic lighter and try to set the adhesive side on fire. Butyl will burn after 10 seconds or so, asphalt will just melt.

I don't believe you should ever use asphalt products in a car. Butyl deadens by adding mass, stiffening and internally by converting vibration to minuscule amounts of heat because of its viscoelastic properties. Asphalt is not viscoelastic so you lose one important function right off the bat.

Asphalt melts at a low temperature. Rubber compounds are added to the asphalt to increase its heat tolerance. Unfortunately, the rubber breaks down over time and with exposure to temperatures much lower than is required to melt the composite material. Eventually the asphalt will melt at much lower temps than it did when new. Obviously this isn't a 100% guaranteed occurrence, just like smoking a pack or two a day isn't guaranteed to kill you. In any case, I've had hundreds of e-mails from people who have had asphalt products fail and exactly zero from those using butyl.

Because asphalt is so much less effective than butyl, you will probably get the similar results without the risks by using much less butyl product. If you are going to buy $100 of asphalt, buy $100 dollars of butyl and spread it around.

Finally, asphalt out-gasses toxic VOCs. So, asphalt is risky, ineffective, a poor value and poisonous. Seems simple to me

Well If this stuff dosent work... how about some eDead V3. I heard it was way better than dynamate, raamat, fatmat....... Since its liquid I could easily install and add more. What are you opinions?

I don't know anything about RattleTrap. To be honest, I've had so much trouble with that whole Corry, PA crowd - FatMat, Sound Destroyer, R-Blox, that I don't even bother talking to them anymore or even ordering products from them to test. Sometimes their customers send me samples and I'm happy to leave it at that.

For all I know, RattleTrap could be decent stuff. "Patented Rubberized Compound" almost always means asphalt, but who knows? Love to see a patent citation though

As a company, FatMat seems to know almost nothing about the products they sell. A perfect example is the "1 Mil PSA(Pressure Sensitive Adhesive)". This is a spec they apparently lifted from the old Dynamat Original without realizing that the manufacturing process used on products like FatMat and RattleTrap makes it impossible to have a distinct PSA - the asphalt or butyl is the adhesive. I also use the term company very loosely since it is a husband and wife selling the stuff out of their house.

Try one of the tests I suggested and let us know what you find out.

I don't mean to be snide, but where did you hear eDead v3 was better than Dynamat or RAAMmat? I know for a while ED reps were trying to spread the word that their new mat was better than Dynamat Xtreme, but they seem to have gotten tired of having me follow them around explaining why that was just one more false statement in a long line from them concerning their sound deadeners.

In any case, liquids can be about as effective as mats, but I think it is safe to say that they will never be better than a mat with a decent foil layer. As far as eDead specifically, it is OK, but not super impressive. I've been testing liquids for the new version of SDS I'm working on. Of particular interest is the fact that it has a higher water content than several other products, making it a poorer value than it would seem by just comparing cost per liquid volume. What you really care about is cured weight - water is cheap and the ess you have to pay to ship, the better.

If you are looking at liquids, consider Second Skin or Lizard Skin. Cascade may be good as well - I haven't seen any yet, but their entire sound deadening line is nice. I've seen a sample of the new version of Spectrum about to be released by Second Skin and it looks really impressive.

I have used Cascade Liquid deadener on 4 vehicles. I am a fan of the stuff. I think I have about a gallon left sitting in my garage.

Not surprised. Cascade stuff tends to be a little expensive, but if you can get a good deal on it, everything I have seen of their's has been top notch.

I diidn't think that the cascade stuff was anymore expensive then most other stuff.

I don't care if v3 is better, Ben's stuff has too many strikes against it in the past for me to ever think about using any deadening product from that loser.

So what would everyone agree on being a good sound deadener..... Im guessing some of the top ones are Raamat, Second Skin, and maybe Brown bread.....

You're right - my perception was based on their butyl mat.

Cross off Brown Bread - asphalt and premium priced asphalt at that. I'd add Cascade VB-Max, Dynamat Xtreme and Hushmat.

After my experience with the liquid Cascade, I am willing to give most of their products a whirl.

This is what it looks like in bucket (sorry for the huge pic).

Applied and drying.

I have used this stuff in doors and on the bottom of cars/trucks. Has worked flawlessly. Easy clean up. The smell is tolerable, hell, it is almost non existent.
