Is there any cheaper product I can use inside my truck, Dynomat is very expensive if doing the whole truck. thx

 

I used B-Quiet Extreme on my rear floor, back wall and doors of my '01 Scab. Works pretty good but I'm not familiar with other products to give an honest compare.

It is sticky as hell and when I applied it in 55*f weather the stuff was almost TOO sticky.

Look for Cascade V-Blok it is also a very good sound deadener. Probably not as great as the Dynamat Extreme or the B-Quiet Extreme/Brown Bread but they all have their strong points and weak points. Some perform better if cold some better if hot and vice vesa. Anyway all of the companies mentioned make a product that if applied correctly will effectively kill road noise, exhaust drone, resonance, and engine roar. Just look around and I am sure you can find something that fits.

Keep in mind that dampng mat only works in reducing rattles and low frequency noise. If your goal is to sound deaden your cab from road, wind, and exhaust noise then damping mat used in conjunction with foam and vinyl/lead mat is ideal.

 

From recent lab test, I believe Second Skin is ranked pretty high!

As Deus pointed out and I failed to mention. Leave it to Deus to kick a man while he is down.

In order to kill certain noises (effectively and economically) you will need to use the companies products that are for that specific application. You can also find that info on each companies website so I did not go into depth on it.

Haz,

I checked out that secondskin site. Gotta say pretty nice product. Haven't compared to the Dynamat performance numbers but from memory it does actually appear to be better. Have you got any of the secondskin installed or heard the before after of it?? Just curious, I already have my truck damped to the max with the Dynamat but I will be trading vehicles in the distant future and may want to go that route. Been looking at that 2005 Mustang hubba, hubba, what a slick looking set of wheels

 

Well when I say lab test I dont mean anything like the numbers the companies post. Im talking specfics here, like actuall dampening capability and adhesion test. The exact numbers were not published because the guy doing it got his company to pay for it and do more extensive test, so he wasn't just about to publish the numbers. However, I believe he did do a ranking of them. It was done by 'The_Spacemonkey' over at www.caraudioforum.com

No I have no used it, but I am thinking about getting some for the hoodliner, firewall, and maybe the roof. I used stormguard just about everywhere else.

 

Go to http://www.mcmaster.com/ and look at page 3240 in the online catalog (just type 3240 in the search box and it'll take you straight to the page.) Scroll down to "Adhesive-Back Damping Sheets," some people use Polymeric Mastic for sound damping their truck cabs.

Alternatively, go to http://www.b-quiet.com/brownbread.html

If you buy the 70 ft^2 roll of brown bread, it's only slightly more expensive than the Mcmaster-Carr stuff, but it comes on a roll instead of in rectangular sheets, which makes it a little easier to put on. And it's specifically designed for what you're using it for (audio damping a vehicle), which the MC stuff isn't.

So far these are the two least expensive sound dampeners (per square foot) that I've been able to find. Personally, I think (no first-hand experience) that the Brown Bread from b-quiet will probably be better for what you want to do with it.
