? about DYNAMAT

[69Rathead]

This same conversation or most of the questions and comments in this thread has been in other threads on http://forums.caraudio.com/vb/index.php and other places. Go on Car audio.com and do a search on "Tar" also do the "peel and seal", "Dynamat", "Asphalt", "Butyl" search...very interesting. Some people who claim to be installers recommend and like using "peel and seal" some don't but people are using it and discussing it...ALOT! Just like this thread. Also people complain about the tar or asphalt smell of Fatmat as well as many other popular sound deadening materials including the "Original" Dynamat which is also asphalt based not Butyl like the extreme. This tells me they are almost all asphalt based with the exception of the butyl ones and therefore probably pretty close to the same in sound deadening based on the thickness/density. A concensus seems to be to use a spray on for the roof area. From what I've read on the forums the following are ASPHALT: Original Dynamat, Fatmat, Brownbread, Edead v1, and probably a few others. BUTYL: Dynamat extreme, Second skin Damplifier. Also go to this link: http://forums.caraudio.com/vb/showth...ighlight=butyl and see the post by Acousticguitar posting up another original post by SIN that contains the following info:

R-blox, Rammat, edead, and b-quiet ultra (formerly brown bread) are all the same product from the same company in different thicknesses.
Fatmat, b-quiet extreme come out of the same plant too, but are a different mixture adhesives.
Accumat by Scoches comes from another company in California that gets their products from overseas.
Peal and seal is roofing product not usually recommended for cars but does the job for most people.
Dynamat laminates their materials in house as does, hushmat. Mostly OEM for the big 3 and overseas.
Madmat buys from Hushmat and private labels it.
Second Skin buys from overseas and from a company called OEM Dampers for private label.
Same with stinger, which also buys from Quiet solutions and OEM Dampers
OEM Dampers does a lot of private label material but only advertises for their line of liquids. Mostly military OEM. If you want are a big enough customer you can buy from OEM Dampers line of bituminous and butyl mats, otherwise its all paint on resins like Select Products blue goo and Dead Skin for Fosgate and Stealthkote. But they do mat at their overseas facilities.
Cascade also makes some of their own products but also imports.
I don't know about dead beat or magic mat though.
The best out of those are butyl mats. Bituminous mats are cheap but have high VOC's due to the asphlat fillers and can be toxic and are always temperature dependant.
hushmat
dynamat extreme
secondskin (though it sounds bit like a touchy subject)
cascade
that would ne my picks

Sorry to take up so much room but I thought it was interesting...but I have not verified any of it! Probably won't bother too either...think I'll just fork out the cash for Dynamat or Fatmat.
