Which one is best? I heard of many and want to see which you guys prefer. I'm looking to dynamat the whole car. The road noise is killing me.

 

Elemental Designs offers a few different styles and is relatively resonably priced. I have used their Edead (forget which version) and have been very happy with it. If you go to their website they have explanations of the different styles and what/how much to use and where to use it.

 

I couldn't be happier with QuietCar's liquid sound dampener. $270 for 5 gals, which is way more than you could use on your entire car, including underneath and fender wells.

 

I went with Raamatt and did my enter vehicle with the mat, ensolite, and adhesive for about $140 shipped. Get a hold of Rick over at Raamatt for pricing. I am going to try edead on my next project. thinking about what I can squeeze into an S2000.

 

+1 used there mat that was about 1$ per sq ft and bought 40 feet. Layered my spare tire area 3 times including over the fenders and had 5-6 feet left over.

 

Good idea is melt down some steel and spray coat it in all the areas you want to be sealed from noise. ha ha.

Actually a good method is to spray rhino liner. No?
