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.

good info to know sean , thanks

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.
