Best sound deadener?

[JENSHAMMER@HOTMAIL.COM]

I am pricing interior sound deadening materials right now... wondering if anyone has a prefference for brand or product name, which is "best" and which is "cheapest" per square foot. Thanks!

I did my entire interior with materials from B-Quiet http://www.b-quiet.com/ last year. It was considerably cheaper than Dynamat. At the time, their leading product was called "Brown Bread". It has been replaced with a newer product named B-Quiet Extreme. Neither are asphalt based. No odor.

I stripped the interior down to bare fiberglass and metal. Removed the old insulation including the mat on the firewall. I did a total interior restoration which included the B-Quiet deadener materials. I'm extremely happy with the results.

I used VComp and LComp, also from B-Quiet, on some areas of the firewall, floor, rear compartment, and console. For the firewall pieces, I created templates from cardboard then cut small pieces of deadener to glue
on the firewall using 3m spray adhesive.

Only one hitch. I covered the inside of the door. The new Corvette America door panels wouldn't fit because of the extra thickness even though it's about 1mm. I had to scrape it off. Not a lot fun.

There are some pictures (not very well organized at this time) of the restoration on my website at http://corvette.sunny-california.com/ if you want to browse all the pictures.

The rest of the car is progressing nicely too. Should be done in 2 months.

Check out www.partsexpress.com. They carry a pretty large selection of sound deadeners, not Dynamat brand, but the same thing. This place primarily supplies car stereo shops and prices are cheaper than I've seen anywhere else. Once on the site, do a search for "Dynamat". I did my vette with sound deadener from here and noticed a big difference. Good luck

www.koolmat.com has a good product. A little pricey. One of the vette mags did an article. Testing found it reduced noise by 23 decibels.

All that stuff is fine for keeping noise and heat out of the cabin--I used it myself. But, to really make it quiet, you have to have thick fiber matting under the carpet. Once the sound gets into the cabin, the surface of those products reflects it. Jute and massed fiber absorbs it.
