I did 2 full layers throughout the entire trunk, one layer on the celing, and 2 layers on the wheel well areas. Didnt do the cabin yet.
I can tell you this though, i had my interior BARE before doing this, only passenger and drivers seat installed. No rear panels, no carpet, no rear seats...nothing at all. Not even door panels. Once i got the trunk and the wheel wells done and went for a ride, it was about 90% as quiet as it was when it was fully asembled. I also then just took that egg carton foam stuff you use like under your bed and put that in the wheel well area behind the big black panels. Now i still have no rear seats, no carpet at all and its a bit quieter than it was fully assembled. I was pretty suprised, and im not even done yet i still need to put it the rest on the roof and the cabin.
I used the eDead v1SE stuff you can buy on ebay. No need for a heat gun or even a roller. Tar smell dissipated after a couple weeks. I bought 120 sq.ft., which is about 60 pounds. Two layers on the floor, two layers on the doors.
Yes, it does make a difference.... I don't turn my stereo on as loud as before. But in a wierd way, now you hear other sounds -- like creaks -- that you didn't before.
I have some material left, and I'm thinking about the wheel wells.... here's the question: How do you do the wheel wells? There's a black plastic liner essentially surrounding the tire; do you put the deadening material on that?
I'm thinking about adding material to the engine-side of the firewall. I can see how that would help reduce engine noise, especially at 4k rpm at 80mph on the freeway.
