Hey gang-
I am looking for options to cool the cockpit of my '78 Corvette. I am also adding a healthier stereo, and would like to block out as much of the road noise as possible. I have seen the heat shield/ sound deadening material cut for Corvettes in the Eckler's catalog. I have also seen the Dynamat stuff, but it seems pretty expensive. Anyone ever heard of this stuff?: http://www.sounddeadeningmaterial.com/home.html
I want to do the entire interior including the firewall, door skins, etc. I don't want to add TONS of weight or make the carpet look like it doesn't belong, but I do want to get rid of the heat and rattles for which the C3 is infamous. Any suggestions? :cheers:
If you want the most pliable material without worrying about weight issues, then Extreme Dynamat is the way to go. The spray on sound deadening materials don't work, and the convential very heavy, tar type stuff is far too messy as well as labor intensive. Dynamat Extreme is much lighter, yet far easier to apply than any others. You can get a bulk pack of Dynamat (2 boxes will do most of a Vette) for approximately $200.00 retail. Hope this helps.

Dynamat ExtremeIS a tar based sound dampener that is labor intensive to apply. Plus, it cost way too much when you can get better product for less money.
Brown-Bread and Raammat60 are both better than Dynamat Extreme and cost a fraction of what Dynamat cost. Dynamat is a dinosaur and hasn’t adjusted to the fact that technology and competition is passing them by.
Just do a search on Ebay and you will find tons of Brown-Bread and Raammat60 for very good prices.
I purchased 70 sq. ft of Brown-Bread on Ebay for $100 USD. The same amount of Raammat60 is about $60 to $80 USD. That much Dynamat Extreme will cost you almost $400 USD. I plan on using Raamatt60 on my next install.
Brown-Bread and Dynamat are both tar based, Raammat is not. Each product I mentioned would perform the same or better than Dynamat will and cost a lot less, so don’t waste your money on Dynamat.
70 sq. ft will be plenty for a C3 Vette. That should do multiple layers too.
Dynamat Extreme is too "labor intensive" to apply? :lol: That's news to me, considering it doesn't take a genius to apply the Dynamat to a surface with a roller, which isn't even totally necessary. I mean, what's so "labor intensive" about peeling and sticking? I won't even mention the other two products in the same breath as Dynamat, considering they aren't in the same league. They cost a fraction of the price due to it being a much lesser product. Btw... ALL sound deadening materials are tar based. ;)
If you don't believe me, call the manufacturer.

:lol: You sound like a dealer who sells Dynamat! Are you? Or were you sold it by some dealer and got the full “salesman pitch”? Either way, that would explain why you are giving out incorrect information about sound dampeners.
For your information Dynamat and Be-Quiet, (makers of Brown-Bread), are the exact same product with only two differences, One is Dynamat has a nifty logo on the foil and second is Dynamat cost a LOT more. Dynamat cost more because they used to monopolize the market, (and still do on a retail standpoint) before it grew to encompass so much competition. Instead of altering their price to compete they send out disinformation to already established dealers to help market their product as “being worth the price because it’s better”. The other products keep prices down by not using tons of distributors like Dynamat does. Lack of overhead makes for a big difference in price. Your incorrect information about Dynamat being best may work on someone who doesn’t know any better however to us who do know better, no offence, but you only sound like a salesman pushing product.
Also, with your analogy you are trying to compare Brown-Bread and Raammat to roofing mastic quality like most salesman do. They are NOT roofing mastic any more than Dynamat is. Dynamat Extreme and Brown-Bread both have the same exact manufacture properties. They both apply the same and they both perform the same, actually Brown-Bread is a tad bit easier to manipulate than Dynamat is and has more metallic flakes but those improvements over Dynamat are minor.
Raammat60 is the only different product to Dynamat and Brown-Bread. It does NOT have a tar based adhesive agent like you incorrectly stated, just like you originally incorrectly eluded to the fact Dynamat wasn’t tar based before changing your comment in your next post. Make up your mind. Raammat has a glue adhesive and is thinner than the afore mentioned products. It however, does posses similar frequency deflecting properties as the others but, due to its thinness, does require more layers for resonance dampening. Raammat is by far the easiest product to apply. It is also the least expensive of the three.
The asphalt adhesive portion of both Dynamat and Brown-Bread are for resonance dampening, the specially designed foil portion with metallic flakes is for frequency dispersal. Together they transform sound and resonance energy into heat for dispersal.
I have used Dynamat Extreme, Brown-Bread and this past weekend helped install Raammat60 on my friends Mercedes. Both Dynamat and Brown-Bread require a roller to apply, they also need a heat gun for proper application, and yes, it is very labor intensive to correctly install both Dynamat and Brown-Bread. The way you stated installing Dynamat was incomplete, therefore incorrect.
So if you do happen to be a dealer, (and I only assume your are since only dealers pass bunk info about Dynamat like that), then that is fine, say anything you like to your customers, but this is a forum for people wanting to learn more about car audio not a sales forum. If on the other hand you honestly don’t know that what your saying is incorrect, then I apologize for being overbearing and hope that you have now been somewhat educated to the truth about Sound Dampening products.
Don’t get me wrong, I have nothing against audio dealers, one of my best friends owns a car audio chain. I just know how some tend to market Dynamat and whereas puffing the goods is fine for selling it in the store, even my friend knows the real deal about lesser expensive, same quality dampening product and would never presume to state that Dynamat is superior in the presence of a knowledgeable car audio crowd.
Again, no offence intended to you, just straightening out the facts.
I treated my doors and cargo area on my C5 coupe with material from http://www.sounddeadeningmaterial.com, and it is definitely quieter. I don't have any hard numbers to back this up, and it's entirely possible that other materials might offer better attenuation per pound; as with all things, YMMV. In my case, it worked well and the price was right. A heat gun, a few beers and a good block of free time all help when installing - it takes a while.
BTW: best way to eliminate road noise on a C5 (I know this doesn't apply in your case): switch from run-flats to normal tires, the difference in sound is night-and-day.
OK, brownbread vs raamatt-which one would stick the best for applying it inside the door-to the outer "door skin"?
I live where it gets cold in the winter nd I'd hate to have it start coming off!
Also on the raamatt-how easy/hard is it to apply? Would I need a heat gun/roller also?
Thanks for any info!

You would not need a heat gun for the Raammat because it sticks with an adhesive rather than an asphalt based compound. All the (tar) compound based sound dampeners require a roller and heat gun to apply it and that makes it tedious work, but their sound dampening performance is excellent!. However, if you don’t use a heat gun and roller on them they will come off.
Either sound dampener will work for you in colder climates but Raammat will by far be easier to apply than Brown-Bread will and will certainly be the most forgiving of errors made in application. I would go with the Raammat and use several layers of it.
Uhh... If I sound like a "retailer selling Dynamat"... what does
your little symposium on the subtle nuances of Raammat and Brown bread make you... someone not trying to sound like a Raammat dealer, but in reality doesn't know the genuine difference between Dynamat and the other competition? Hmmm... quite odd... for a second there.. it sounded like you were promoting this other product and throwing out information about products which you know very little about... I, my friend, sell two of the products you mentioned... wholesale cost is EXACTLY the same... Get your roller out... it's gonna be a "difficult install"

LMAO, I KNEW you sounded like a Dynamat dealer! :lol:

It makes me someone who knows about these sound dampening products from first hand experience with them and am giving an honest, non-bias viewpoint on them. Remember, this is a car audio forum for people to come and learn about different aspects of car audio, that includes good products and good prices. This is a place to learn how to get the most audio boom for the buck, not to promote a product you sell.

:lol: I gave you the "genuine difference" between the brands in my earlier post. THERE IS NO DIFFERENCE between Dynamat and Brown-Bread other than logo and price. Well, like I said there is a few more metallic flakes in the Brown-Bread foil but that really isn't much of an improvement. All in all they are the same product. Refusing to see or admit to that is your problem not ours. ;)

Ummm....I wrote a dissertation length post on the detailed differences of the three products in question and you say I know very little about them? :lol: :rolleyes:

Well we know that one of those products is Dynamat, I wonder, which of those two products do you make the most profit off of after your retail markup? Could it be the one with “name brand” recognition perhaps? Hmmmm.
I can see the sales pitch now......”Why yes son, Dynamat is more expensive because it is better, you always pay more for the better product. Trust me, if you give me that wad of cash and put this overpriced Dynamat in your Honda Accord Type R then it will make your stereo TWICE as loud! You will out pound all the other ricers...err...I mean other car audio enthusiasts on the road. It also adds 50 HP! It’s true! Honest! No lie!
Then you need to put these neon’s in it too because it's cool. Now son, how about some JL subs?” :lol:

I don't even know what that means. :lol:
Look friend, we have beaten this topic to death ok? It is obvious that I know what I am saying, and besides, there is no need to feel embarrassed or upset about being corrected here. My point in all of this is simply this, Dynamat, Brown-Bread and Raammat are all good products, no one is saying Dynamat isn’t quality stuff, it is. I am just stating that why would you want to pay double the price for something that is no different than another product that will do exactly the same thing for less?
People come to forums like this to get knowledgeable info on car audio so they can make the best choices possible for the price they can afford. They can get plenty of sales pitches in the audio shops, that’s why they come here, to get unbiased info.
I’m sure you are extremely knowledgeable about many car audio subjects and I look forward to discussing them with you in the future. I’m sure there are many things I can learn from you; just realize when it is time for yourself to learn as well.
No hard feeling, look forward to talking audio with you.
Best wishes, your pal, Nomad :seeya
Re: Heat Shield/Sound Deadener options? (Z oooooo 6)
OK, now another question.....is the rammat considerably thicker? Would a couple layers fit OK?
Also, I know I was going to install it inside the doors-but I saw where ya'll just put it under the door panel; will under the door panel work real well-in sound dampening/fitment under the panel?
Thanks for the con't info!

No, Raammat is actually thinner than the others products mentioned. It is simply easier to apply and is cheaper but still has most of the performance characteristics of the others mentioned.
Yes, you will need multiple layers of the stuff no matter what brand sound dampener you use. In fact I have over 4 layers of Brown-Bread covering my entire C4 Vette. The more layers the better the results. You should have no trouble getting the door panel back on after 3 or so layers.
I did the inside door frame, inside the door panel and put ¼” foam padding between the door panel and doorframe. I was still able to get the door panel back on with minimal fuss.
