So now is the time to sound deaden the inside of my car, but with so many choices these days which one should I go with. Dynamat, Fatmat, or edead. Anyone used any of these? Do they really work?
sound deadening dilema
- Thread starter rusted-resto
- Start date
i went with dynamat extreme (not the black stuff, its the chrome foil looking stuff). my entire floor is covered with it and it cut out almost all the road noise. i'm very pleased with the results. the only drawback is this stuff is really heavy. but i think its worth it. fatmat is similar but is made with a cheaper material that doesnt work as well.
I think you need to use a larger font size. I had a lot of trouble reading your post.
Back to your question, I am almost finished applying this product to the interior of my car. I am very impressed with the results, the floors sound like they are a foot thick.

You can get by using the insulating wraps sold at the hardware stores for home water heaters. Unroll it, and cut off the excess, sometimes the carpet may even fit better.

Just my two cents, but I would recommend a company named second skin audio http://secondskinaudio.com. I just finished my daily driver with spectum (a liquid) and damplifier (adhesive mats). Both would work in your case. The spectrum doesn't seem to have any problems bonding to paint, metal or plastic. It can be used on the interior as well as the exterior as an undercoating. That being said it has different properties than a standard undercoating. The damplifier is comparable to dynamat extreme and rated to around 450 degrees.
The products are cheaper than dynamat, are not repackaged products like some 'manufacturers.' Anthony, the owner, picks up the phone himself and has been great to deal with. He also offers some B-stock products at a reasonable savings. They also offer sound absorbing materials which are different than deadening products. BTW, Pimp My Ride just signed on to use his stuff (not sure if that's good or bad). And no, I have no affiliation with the company, I'm just a happy customer.

some of you guys like to pay too much. Just about all of the 'specialized' soud deadener products have been on the market for years, just used in different applications. The guys that own Dynamat are laughing all the way to the bank. They probably are good friends with the guys at Custom Autosound. They have shared tactics on how to sell old technology at ripoff prices. Dynamat sells gutter liner for $30 a square foot, and Cusotm Autosound sells AM/FM/cassette radios (that don't work half the time) for $250. Sheesh, anyway, enough ranting.
There is a product available at Lowe's, probably also at Home Depot, called Peel and Seal. It comes in a 6" x 25' roll. Same exact stuff as Dynamat. I think it was only about $10 a roll though. Its a self adhesive rubber/polymer/asphalt sheet with an aluminum facer on it. I put it in the roof and doors of my 65 F100 (a.k.a. the tin can), and it worked great.

I finished spraying the entire interior of my 66 fastback with 2 coats of Eastwoods Rust Encapsulator and 4 coats of SecondSkin. There appeared to be no problems with adhesion. The SecondSkin is probably enough sound deadening for most, but I am really shooting to make the interior as quiet as possible therefore I am also going to apply some type of matting. Like others I am reluctant to send money for the sound mat type of materials thinking there has to be cheaper alternatives. I think I will check Lowes and Home Depot as mentioned by someone else.

302 is right, if your looking for a cheap way out. Many companies are repackaging products such as peel 'n' seal. What I can tell you is that it's an asphalt polymer sheet with many of the properties that the mustangs' deadener originally had with the addition of the adhesive and mylar/foil facing. Asphalt based products are old technology and do have some effect on deadening. The product 302 refers to will achieve some of the desired effect, however in the car audio industry it is known for peeling off doors and roofs due to poor adhesion properties in high temps. Second skin, dynamat and several others have addressed these problems and developed new compounds which are more efficient and at deadening. Several of these products have been adopted for commercial and military use.
As I think I mentioned earlier, there are deadening products and absorbing products. The deadeners slow down the transfer of sound, while the absorbers do just that, absorb certain frequencies. Together, you could make make your classic almost as quiet as a new Mustang. Depends on the end result you want. The liquids are great if you have the car apart because they get in every crack. Two gallons of something like spectrum would cover the interior floorboards and firewall with a couple coats and the result is twice as good as the old asphalt sound deadener. Good luck whatever you use.
