we compared them at NEBF, with pics and everything...its exactly that same

and Plurr, i love the stuff and wouldnt use anything else.....

comparing how they look doesn't mean they are exactly the same. If I had non asphalt mat, they could have looked and felt exactly the same, but one could be better than the other. You wouldn't know unless you conducted tests.

Someone conducted a "Sound Deadener Showdown" and posted the results here.

http://www.sounddeadenershowdown.com/

Fat Mat is included in the list of deadeners tested. The article is lengthy and hard to find specific deadeners so here are some excerts about FatMat. Go further into the article to see the different tests done to determine how good each deadener truely is.

Peel & Seal and Jiffy Seal are roofing products that fit in this category. Many people buy them for sound deadening. Of the products I tested, B-Quiet Extreme, Brown Bread, Dynamat Original, eDead v1, eDead v1SE and FatMat are in this group. Many people report great success with one or more of these mats. They are certainly the cheapest option. If you know your car will never be exposed to extreme heat or cold, they may work for you. I'm not suggesting that all of these products have a 100% failure rate under extreme conditions, but I do believe they are risky. Their narrower temperature range also means they will be less effective the farther they get from room temperature. I would not use any of these products in my car.

Afterseeing CorvetteCrazy'* car...and seeing the price of the stuff...I'm thinking I'd do it if I pulled my car apart again.

After reading the comparison I am leading towards the RAAMaudio product. I will just have to wait a little longer. It gets nice and warm here in Oklahoma in the summer, and I don't want to worry about it losing effectiveness in the heat.

Thanks for all the great input.
