dynamat or?

[jeff hanson]

Should have the car back very soon and need to get it insulated. It is one of the few things that I don't have yet. What does everyone think. Who's, why and where is the best bang for the buck? I have been thinking RAAM mat but can't get a hold of anyone. Anyone know what's up with that? Suggestion's please and thank you! BTW, let's try to keep this simple, I don't need a phd in insulation, just want to get it done.:thumbsup:

I've got Fatmat in my car. I love it. I got the super (butyl) type. It sticks awesome. And was VERY cheap. I got it on ebay.

if you ever plan on any other mods do not do dynamat or other stick on deadners, i just did a quadra link in a dynamtted car and it took longer to get the dynamat off then it did to install the upper pockets

I just used the Thermo-Tec stuff. Be sure to use some sort of roller tool to apply or your fingers will look like sausages by the time you are half done.

Have you guys ever used some stuff called Brown Bread?

RAAMAudio, hands down, bar none.

I used a product called second skin audio.they to have a web site explaining benfits of their product over someone elses.

Thank you novanutcase for posting that article. while it was not done in a lab that is more info on sound deadeners than 99% of people would have bothered to research, THANKS

That showdown was created by the guys at Second Skin apparently, so it's a little one sided.............

i have dynamat in my mustang and love it. only sound deading i ever removed was factory type dry ice and a hammer works great for that.im sure if you use a torch or heat gun with a putty knife you can get the stick down type up.

I didn't think that was the case, but I have been emailing back and forth with Don and can ask. I do laser vibration measurements for a living and we are discussing methods for doing a damping comparison between the different products. His tests currently mostly have to do with adhesion since a constrained mass layer dampening material can't work if it doesn't touch. He wants my help to make a better showdown in the not so distant future.

As for what I think is the most effective? I would say it depends on how it is applied. Second skin is thicker and better than Raamat, however it is more expensive. If you are just putting down a single layer over everything (which I would argue isn't the right way to do it) I wouldn't hesitate to choose Second Skin. However, Raamat is cheaper per sqft and will allow you to double up where necessary providing an advantage. Personally I normally use Raamat, but from the perspective of recommendations both are great products! Another thing, Ant from 2ndSkin and Rick from Raamat are also both great guys and will give you great support. I cannot say that about any of the other products, and many have customer support horror stories.

One other note. The mats only prevent your panels from adding noise. Adding an acoustic barrier like Ensolite (from Raamaudio) will help to absorb the noise that is already in the car making it quieter. Using both together can be very effective. I don't own a vehicle that doesn't get a copious layer of both.

Another side benefit of good damping is improving the imaging of your midrange and the output of your midbass. Having a sealed door (if that is where your speakers are mounted) can really up your output and help your clarity. I realize that sonic bliss from a sound system isn't the focus here, but having a crappy sounding stereo in something else that is completely customized seems strange to me as well. All of my installs are Sound Quality focused and not SPL focused.

*sorry for bumping up an old thread, but since I figured this is something someone will search for I thought it would be beneficial to update it. If anyone ever has any deadening or stereo component questions I would be more than happy to field PM's.

Paul we used that in a friends car and it worked fine at a great price. He doubled and in some cases tripple layered (the wheel wells, ect) and he really likes the results.
