sound deadener

Just wondering what you guys think is the best type of sound deadening material.  I've used dynamat extreme before, but I've heard of a lot of other products and people claiming that they are better than the others, etc.  Also, I've heard of some paint-on type products that are supposed to work well too.  I would like to know what product you think is the best performing overall and also the best product for the money.  If you guys know any sites where to get this stuff for a good price, please list those as well because I am looking to purchase some in the near future. Thanks.

www.b-quiet.com  is where you can get the brown bread.  Only took 9 days from Canada to SoCal.  Hint:  Pay for the expediting.  Bread is less expensive than Dynamat Extreme. 

Used both on the same van 118sqft combined - didnt do the roof though.  Dynamat Extreme is a little more dense than the Bread.  Bread is really messy compared to Extreme - Bread got under my fingernails while Extreme didnt.  Bread went on easier - less dense.  Its really hard to compare the effectiveness of both unless you take two same vehicles and apply the products and measure noise levels after.  However, in working with both and observing the materials, I would prefer the Dynamat.  Price is the offset.  If youre gonna $pend the time to rip out your entire interior, might as well be confident in the product before you rein$tall your interior.   

The BEST is, believe it or not-- LEAD. Lead sheeting has been used extensively on diesel pickups. Check theforums at www.turbodieselregister.com

The sheet lead comes in malleable rolls which can be formed around irregular shapes by hand or with tools

what were you doing to get it under your fingernails? lol...

brown bread is not the equivalent to Dynamat Xtreme, and that is why it is less dense...brown bread is the equivalent to regular Dynamat, and thus the density difference...I believe they do offer a denser product as well, equivalent to the Dynamat Extreme, but have am not sure because I havent ever really required anything that dense...

Exactly my point - read it closer.... 

"Bread is really messy compared to Extreme - Bread got under my fingernails while Extreme didnt." 

I use Brown Bread all installs I do.  It usaully takes 4 days to get here (WI) from Canada with no shipping add-ons.  I'm sure they offer free shipping with all purchases.  I have used Dyanmat Extreme in the past and really see no difference except a huge hit in my wallet.  Go with 70 sq. ft B-Quiet Brown Bread $159.99 that would cost around $400.00 for 70 sq. ft. of Dynamat.  Heck double layer it up if you want.

Check out RAAMmat. http://www.raamaudio.com   About $85 shipped for 62.5 sq. ft. of 60mm.  Rick is a nice guy.  Great service.

Just to clarify to other members what " sound deadner " is. The material is used for application to add weight to panels so there is less vibrations & reduces outside noises from getting inside of the vehicle. When applied properly, this "membrane" can reduce unwanted road noise and can increase your SPL of your sound system depending on where it is applied and how many layers. If speed is what you are after, then sound proofing your ride is not a good idea as is a sound system is not a good idea either for a race track car.

Thanks for reading my 2 c's.
