I found some stuff from McMaster-Carr called Hi-Temp Mastic (PN# 9709T18 - $12.79/sheet for a 32"x54" sheet) It's an asphalt based material much like Dynamat but ALOT CHEAPER. It's a peel and stick application and a little heat will allow you to press it into all the nooks and crannies just like Dynamat. It also weighs about 9lbs/sheet so it's not exactly light. ***(I can see LIGHTNINROD jumping up and down now that I'm adding weight instead of removing it)***

This weekend I took a few hours to put this stuff in, quite simply, it works. I put five sheet in (one per door, two for the floor, and one for the back wall) and plan to put one on the roof (just gotta take the time to drop the headliner) Got to take it for a my morning commute on the interstate and noticed that the highway noise was reduced and the truck has a solid "feel" to it when the doors are closed now. Not a bad investment for about $90 including shipping.

Just thought I would pass this one to you guys that would like to say a few bucks. Now I just gotta get back to working on the stereo.

On a side note, my apartment neighbor came by when I had the interior gutted and nearly freaked, something about claiming insanity for rippin' out the interior of a $32K truck or something, I was to busy rippin' stuff out. I've done this to every vehicle I've ever owned and will continue to do so until I own a Lexus or Acura, or that 911TT.

 

Does this stuff smell? Does it come off the carpets or seats if you accidentally get some in the fabric?

 

I used it on my doors and it seemed OK, I don't know if it is as effective as the good stuff though........doesn't smell

 

It' won't harm you carpet, won't stick to it for that matter. The outside of it feels like almost rubber. It's got to be some asphalt rubber mix. It will not do the job of say Super Dynamat but then again it doesn't weigh as much as Super either. Mass loading is what kills noise.

 

CornerCarver, when you say you 'put it in the doors' did you put it inside the door attaching it to the outside door panel or did you attach it to the inner door panel?

 

Inside the door on the outer wall (door skin) as best I could. There's not exactly alot of room to work in there. I then slapped a few small pieces on the inside (door panel side) and then replaced the thin plastic skin with one piece of mastic. I used the plastic door skin cover for a template. I still had a piece about 12"x16" leftover from each door.

I am appalled! You did this so you would have an EXCUSE on the 26th.

I'm surprised, nay, shocked that you didn't use DENIM !

I was looking into the same stuff. Is it worth it? How big of a difference in outside sound levels, if you could give an example.

 

I've notice small bumps are now muffled "thumps". There are now no small "creaks" when going over railroad tracks. I've always been **** about noises since I've always had some serious stereo systems and road noise is a BIG problem with high-end systems. My GF always says that I "hear stuff." It's a noticable difference to me since I drive it everyday. My GF also stated she heard a difference. It's not an "OMIGOD" effect since it was only one-layer, but I'm sure if you went with multiple layers then it would be even quieter. Needless to say, I'm happy with the results I got for $90 and I still haven't even done the roof (this should only matter when it rains).

BTW, to get layers to stick to each other you really have to apply the heat. This is where the dampning material such as the old Stinger Pro really shines as mutiple layers are a piece of cake.

 

I did two layers on both doors, back panel,and the floor. I have to say that it's well worth the money and time. You can still hear things,but not very noticable minus the screaming s/c ,and the mufflers. The quality is like going from a civic to a caddy,as far as the noise level. I love it but I think if I ever buy another car I will pay for someone to install it.
