Brown Bread vs Dynamat vs others

[tkd_q45]

Does anyone have any long term experience with Brown Bread? I'm wondering if there are any strange oders/gas off from this product. Someone in another forum had mentioned this as a possible problem.

I don't care to do any of those spray solutions. I did this once in a Miata I once had and I felt it made more of a mess than anything else. I did put Phoenix Gold matts in the doors and they really added a nice "thunkiness" to the doors. Made the doors feel much higher quality.

I'll be starting with the insides of the doors as that what others (G50) have stated as best bang for the buck but I will pobably be doing much of trunk as well.

Who's a good supplier of noise suppression? Should I just go Ebay?

buying on ebay = not so good because it's heavy stuff and shipping is a lot. dynamat is way over priced. you have to consider what type of noise suppression is right for you. if you have a big boomy system and it rattles everything then having dynamat or something like that is a must, at least in the surrounding area of the speakers. the stuff dampens a lot but because of the weight it becomes a big drag (oh what a play on words). if you're not going to have a big boomy sound system in your car i would suggest covering only the immediate surrounding area of the speaker with dynamat (or similarly go spend next to nothing on some stuff from home depot), and then go buy some foam and fill up the empty spaces that resonate and create all kinds of noise in the car. foam is cheap, weighs very little and is very good at suppressing road noise. since i'm into light weight and more performance this was something i did. it works great. on the car i had before this i ended up putting on like 50 lbs of extra weight in dynamat alone, and then probably damn near 100 more with the system and all that stuff. it sounded nice but was way overpriced (especially what i paid for stupid dynamat extreme... i will never buy that crap again... they are insane. it is the same as roofing stuff but costs 1000X as much. home depot is the answer... what you can get there is exactly the same. exactly.)

You didn't find that the Home Depot material had any kinds of bad smells in warm weather? I find it hard to believe that it would perform as well (thought I know dyanmat to be overpriced).

I've always have found going with the middle ground to be where the value is (generally). I'm hesitant to do foam as I don't know what moisture drains I might be clogging or what other disassembly/access I may be negatively affecting.

I've only used Dynamat, but I think it's all there wasway back then .

In a couple other threads it seems Brown Bread is considered as good or worth the savings.

I have strong faith in the performance of Dyna-mat, I use three of their products in my car, Extreme, premium, and Dyna-linermax. It is a bit pricey, but you can find a good salesman build a relationship though repated purchases, loyalty and get great savings. Cascade Audio Engineering also make great products, the are a local Oregon company. I don't have as much experience with these products but they are just as effective. I've never heard of this brown bread stuff.It all depends on the purpose for your sound dampening needs. Are you trying to quiet down the interior of the car? or make the speakers more efficient by reducing flex of panels in and around the speaker.

a lot of cars aleardy come with some foam in the rear tire wells and other areas... i think adding more won't hurt. i would just stay away from adding it to the door panels and areas the windows roll in and what not. not only because it would restrict the window rolling down, but also because a lot of water goes through there.

if you can find a cheap alternative to dynamat that doesn't smell then go for that. it's not like dynamat is this wonderful product that no one else can reproduce. it's just tar basically. i mean you could do that same thing with a bunch of sticky tac or anything with the same type of consistency. i just suggested foam as a lighter alternative...

i never tried the home depot stuff actually, but i'm sure there is something out there that will not smell so bad. hell i would prefer the smell to paying that much for that dynamat again, because then every time i smelled it it would remind me that i saved a ton of money.

I have a customer who does AC/refrigeration for commercial buildings, he says their is a similar product that he uses but it doesn't come in as big of sheets as dynamat. I'm sure that there are some marketing pricing increases due to the distribution and promotion of the dynamat name. But what do you expect everybody seems to have brand recognition with dynamat so they most be doing something right.

[hysteria]

yeah. it seems like they just took over the market with what they made because dynamat is the standard... everyone knows them. i wonder how they got everyone to advertise their product so much...

[lancefloyd]

the extreme dynamat is some pretty special stuff. Its not tar or anything like it. If anything, its more like a double sided sticky tape from 3M, with a heavy foil on the other side. I buy it at cost. Its about 60% markup, so if you can get a nice salesperson to hook you up through package dealing, you should be able to get about a 20% or more cut off retail. And oh, I use the sorta expanding foam on all my cars from Lowe's

[hysteria]

eh i don't know how far from tar it is... have you ever gotten it on your clothes? it behaves very similar to tar. it's not quite as bad but trust me never work with this stuff in clothes you like... of course i installed an enormous amount in my car and sat on some of it while putting other down... that stuff will never come out of the shorts i had on... without something highly toxic at least. good thing they were old clothes...

I've been preaching this for awhile now. Expanding foam can be used to fill anything you want, competely solid. It is water proof, and does NOT promote sound transmission

Now, spray on rubeer is another option. It can usually be found at hardwhere stores. It basically does the same thing as Dynamat by adding an elastic layer of rubber to whereever you spray it, which demotes resonance.

[lancefloyd]

lol i too have ruined a pair of shorts by sitting on some dynamat... Its somethin all right.
