Title: Sound deadening stuff...
Post by: Skunksmash on July 20, 2008, 07:27:24 am
I was reading the main website, where all the how to articles are posted. Is the guy with the yellow truck still around here? He used something called "Brown Bread" to get rid of unwanted road noise. I just wanted to ask him how it worked out, because i was considering using it as well when i paint my truck. I would be really nice to have a truck that was quieter than it was from the factory.

I have a yellow truck but it's not the one you speak of. Brown Bread though is a good product. There are others out there too that as much or even more effective for the same or less cost. One product is B-Quiet. It should be on Ebay from the distributor who sells it. Another is Rammat.

What I did was take 1/2" carpet underlay and did the whole floor of my truck and then put the factory carpet overtop. I hot-glued it in place and it formed over the floor just fine. It made quite a noticeable difference in sound attenuation. Cost me something like $20 I think.

When I cover my floor board, firewall, inner/outer door skins, and roof with a dampening product, I'm gonna use Second Skin Damplifier sheets.  I've heard a lot of very good things about performance/dollar.  Apparently its the same(or better) stuff as Dynamat Xtreme at less than half the cost.

Hmm. Which one is the very best? If money were not an issue? I would probly just fork out the money and get the best one cause i really dont want to hear any noise at all.

Brown Bread is made by B-Quiet.  The owner of the yellow truck is still here. (bigblock73) and he has posted his truck pics on his site 73-87.com
I know of several people using brown bread (N2TRUX) on here is using it and had driven his.  I would recommend it over higher priced dynomat.
You can find it here: http://www.b-quiet.com/brownbread.html

Oh right, duh, what was I thinking. In the back of my head I thought the two products were related but was having a brain fart. I kinda know the guy who owns B-Quiet. Good product for sure.

Sounds like they are all pretty much equal. I mean all they do is use that gooey rubber stuff on the back of a very thin piece of metal, right?

Yep, pretty much.  So go with the cheapest one.

But don't use roofing underlayment like I know some have.  The materials used in this stuff put off an terrible odor when heated.  According to Second Skin, all proper car dampeners come in sheets, whereas roofing underlayment comes in rolls.  So any "car dampener" that comes in a roll is just repackaged roofing underlayment.

It probly will not ever matter, but just out of curiosity how hard would it bee to remove all this stuff?

Remove the carpet, seat, and door panels to lay it down (easy), remove the dampener after it's on (hard).

Ok well for those of you that have used this on one of these trucks, how would you rate it? Does it cancel out nearly all road noise? Maybe it cuts it in half? What's your opinion?

The website says Brownbread has been discontinued. They have replaced it with B-Quiet Extreme.

Are you satisfied with it? Do you think it cancels out a lot of noise, or just a little bit?

I have not done this to any vehicle I own yet.  But I have heard from several people who have and the overall concensus is it makes very noticeable difference in interior noise if you hit the common trouble spots (door skins inner/outer, floorboard, firewall, roof, area behind seat) and get at least 75% coverage.  Also I've heard people say other than helping with noise it also makes it seem more "solid" and "refined" overall.  A buddy who used dynamat on a '76 stepside w/tunnel-ram 350 also said it blocks a noticeable amount more firewall heat than jute alone.

The catch is, when you cancel out most vibrations in the sheet metal, things like wind noise, engine noise, and interior rattles become much more apparent.  So I think the thing to do is moderate rather than eliminate structural resonance.  I am going to draw the line at about 80 sq-ft of dampening material and I'll put on fresh weatherstriping at the same time.

I guess then you have to start chasing all those interior rattles, huh? Did that on my Mustang, and it's an uphill/losing battle.
