    Just htought i would give everyone an old tip. It may have been covered but here is a cheap solution for sound deading your cab.

    Roofing tar paper and 3M spray adhisive. 2 layers is equal to dynomat and is 1/10 the cost.
    I have had good luck with it and it applys easy.....

    Polymeric Mastic from McMaster Carr is also a good economical choice, and it already has a strong adhesive on it!!! About 1/6th the price of Dynamat IIRC.

    I've been spending a LOT of quality time with this product lately. So far I've installed two layers throughout the Suburban floor area (something like 5 or 6 full sheets) and I still want to do the quarterpanels and inner door skins.

    It's already made a BIG difference in noise reduction. /forums/images/graemlins/grin.gif

    Yeah Greg is right there, I put about 10 sheets in my Jimmy. WOW what a difference! /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif Just use a heat gun to make sure it sticks well, and it helps it fit to the contours.

    thanks for the info greg, my current rig is noisy as hell, and I dont mind it at all.. but at some point when the S-10 cab goes on Im gonna make it sorta civilized (yeah, trying to get the woman to wheel with me!) so maybe this would help. /forums/images/graemlins/grin.gif I plan on Line-X'ing the cab inside and out, that oughta help quite a bit too. At any rate, thanks,

    I used some of that stuff in my roof of my s-10. I used some noise killer paint, some peel & seal roofing material as well as the padding (more to insulate heat than sound but it does help the sound some as well).

    I just finished doing the floor of my s-10 in the same way (4 layers of the paint, 1 of the roofing material, 2 layers of padding, and the carpet). Along with the other work already done I almost can't hear my exhaust leak /forums/images/graemlins/eek.gif. Next I just have to do carpet and padding on the back wall and the doors...should sound if not like a Lexus maybe more like a new truck /forums/images/graemlins/thumb.gif. The only thing I have had a hard time getting rid of is wind noise around the windshield...don't know what I can do about that.
     
  7. I bought 2 70 sq foot rolls of brown bread and covered the entire floor and up the sides of my Sub. Didnt have enough for the doors or roof, but it made a big difference.

    I am having a difficult time finding that product on their web page, can you give me a link to the actual page of the product? /forums/images/graemlins/thumb.gif

    i tried lytherm. kind of expensive, but it is super quiet inside. extra benefit is that no heat comes throught either. nice in texas!
