I tapped on the metal part of the wheel wells and even where i dynamtted they still still ring/vibrate like crazy. Almost like there is a cavity between the exterior wheel well and the wheel well in the hatch.

It dulled it somewhat... Almost to a point you can't hear it. But, you still can. I plan on putting some FatMat behind the plastic liner as another member stated... just waiting for FatMat to show up. It's worth the $20 of Fat Mat to try. Plus there was a couple pieced together areas in the hatch I want to rework so the extra material will allow me to do that. $60 total is a cheap way to minimize / deaden the noise in my opinion. Plus, the stereo does sound better after this treatment.

Frost King

The question of whether or not to put Frost King reminds me of a mafia movie..Someone help me with the name I think it was Cassino..anyway the FBI has rounded up a bunch of mafia dons and they are now trying to cover their trails..they have a meeting and are deciding who might talk and so who to whack and who not to whack..

They come up with a bunch of names and agree to whack them..then one name comes up..one don says, "He is a stand up guy no problems with him" The next agrees and says, "Ya he's always been a good soldier" but the third says, "Ya well he I agree he's always been a good man..but the way I figure it..why take a chance?!!"

Next thing you know he's whacked..(What was that movie?)

Same with frost king.....why take a chance?

ill keep a close watch. first sign of trouble its out. But im guessing that aint the case.

I was baking in the oven some rolls at 370 Degrees. So I decided to test a piece of Frost King. I turned the oven off after placing a strip on a metal cooking pan. Left it in there for 30 minutes. No smell. Easily removed as if it was 60 degrees. No gue. nothing. The shiny aluminized side had stayed about normal to the touch. The underside was normal . Took it outside for a smell test. It was fine. In appearance and everything. I dont believe this was the product used in the post where a friend had a poor expirience in a heated condition. For this puts end to this. Still will check but i dont anticipate a problem.

Good test right here. Im thinking you saved people a bunch of cash with the Frost King discovery.

Great idea. Awesome that it looks like this stuff is going to work. Perfect.

Finally had a few minutes last night to download pictures off my camera.

I first bought the FatMat Trunk Kit, 5 sheets @ 18 x 36. This covered the fender humps, the front area behind the seats, and up and over the axle beam. But that was it.

DCNISMO · 03-30-2012, 02:15 PM

Somebody should sell a sound proofing kit for the Z with the precut pieces of fatmat or dynamat all ready to go. I'm lazy, I would buy a kit like that.

wilsonp · 03-30-2012, 05:30 PM

I read an article (Second Skin?) that said 100% coverage was overkill, and that covering the center of most panels would be enough to deaden vibrations. After that, a sound absorber was recommended.

Does anyone think you don't really need 100% coverage?

Evil Sports · 03-30-2012, 06:47 PM

Is there really any reason to keep those foam panels in the back

Evil, i was thinking the same. Actually, the area around the spare is a nice unseen storage compartment once you remove the spare. I added those pieces of carpet insulation behind those panels also. They probably help with some sound insulating from the wheel wells though.

Evil Sports · 03-31-2012, 09:31 AM

What if I dont want to remove my spare. My Bose Sub sits on top of it

maurim3 · 04-04-2012, 08:31 AM

Hey guys.. do you think this type of sound absorber would work ?

I would think any cloth like material would certainly help. Now add Dynamat or Fat Mat. The more = better.

Whatcha got there would probably help with high frequency sound control. Dynamat helps with panel vibrations. For total control you would probably also need something like Luxury Liner Pro, which is a closed cell foam bonded to a mass loaded vinyl, which helps control low frequency tones.
