sound reduction in the cab?
 

I am wondering what product will work simular to Dynamat but be less expensive? I am trying to control the sound and heat in the cab. I want to enclose the entire cab area. Any help would be appreciated. :)

3M undercoating from Napa will reduce noise levels, or any undercoating for that matter, but not work *as well* as dynamat. Look around, dynamat isn't the *only* sound deadening material out there.

Brown Bread works great and is a lot cheaper than Dynamat. I purchased some on Ebay.

I've been checking on the Brown Bread and that looks pretty good and a bit cheaper. Fatmat seems to be another competitior, just wondering what experiences have been had with all three. I live in an area that gets HOT, any of you in hot climates have any experience with any of the products smelling? I'm not looking to be cheap but I want the best value. Anybody on here sell this stuff.

MAN, WHERE WERE U IN JAN. ?

HAD 2 BIG BOXES OF DYNAMAT

APPROX. 80 SQ. FEET TOTAL

COULDN'T EVEN GET $100 + SHIPPING

SETTLED 4 $100 SHIPPED ( $30 2 SHIP )

"I'M ALWAYS IN THE WRONG PLACE AT THE WRONG TIME"

:banghead:

My timing is great, i think I was crawling out from under a rock in Jan.

I have used Dynomat and fatmat. They seem to be almost the same stuff. 96 degrees today and no smell. The Dynomat smelled when I first put it in but after a couple of days it's ok.

Did yall paint or do anything special before the mat went down?

Two words- Brown Bread! There is a guy an Ebay that ships it the same day you order. It's the cheapest "real" sound deadner out there and according to everyone that has installed it they love how easy it is to shape.

Here are a couple of threads about it-Brown Bread
Sound Deadner

I recently had power windows and power locks installed in my 77 Cheyenne. I had the sop put Brown Bread inside the doors, and behind the door panels. It made a "huge" difference in how solid the doors sound and feel when they shut. It also made the cab much tighter and quiter. I can't wait to do the rest of the cab... :cool:

Does anyone know if you can get brown bread right in your own home town at some chain store or something, or have you only seen it on e-bay? I am very interested as the burb should be coming back to me this month and this is one of the first things I want to tackle. It sounds like from the post that it makes quite a difference in all around feel and sound regardless of the brand.

Glad you asked this question lewi!! I am getting ready to tackle this same task myself, and had the same questions...reference dynamat, and whether to paint before applying. Will be watching this thread for more info!!

I am not aware of any "local" dealers of Brown Bread.
If ordered through E-Bay the guy get's it to you in about 3-5 days!

I ordered from him 2 separates times and both times it was at my door in 4 days. :metal:

HERE'S the ad on E-Bay.$139.00 for a 70sq/ft roll.

There is a spray in or roll on liner called cool car, but I believe they changed their name to Lizard skins, It looks like a bed liner when it is installed but it is a sound deadner and heat block so it keeps the inside of the cab cool too. I know a shop that uses this and it is good stuff. It comes in a 5 gal for about $150. I plan on using it because you dont have to cut and fit like brown bead. Just apply it with a brush or roller or if you have a undercoating spray gun and compressor its easy.

Thanks for the replies, At this point it looks like brown bread is the winner but I am definatly open to more opinions. I am getting the truck back within the week after the new motor install and this is my next "to-do" as the AC will be working now..I am hoping that I'll get a little cooling effect from it in addition to the sound reduction.

So Bobby, how many sq feet did you end up using?

Saw you did the bed, did you do the bedsides?

What about the two layers they talk about. I'm all set to put this stuff in the doors, but dont want to go too crazy in case it traps moisture.........i suppose it could also detract from value, but I guess I'll have to get over that.......

You still happy with the results?

On the cab floor, it is a good idea to use your sound deadener under the carpet, and then some of the spray on stuff unedneath. Inside the front fenderwells is another spot seldom done in a truck, but it helps there too.

Anyone tried the sound absorber from Mcmaster-Carr? It's a little bit more expensive than Brown Bread, but it can be had in smaller qtys. Page 3266 @ Mcmaster.com for anyone interested.

I covered just about every surface in the truck.
Inside the doors,the bed,bedsides,kickpanel area's.

I used 1.5 roll's,maybe a little less.
I figure if you do the bed,inside doors,wheel wells one roll should be enough.

I only applied one layer.I guess the more you use the better the results.
I'm impressed with just one layer.

Here's another option. I used a product called RAAMmat. Check out their site if you want to know about the product. I've had it in for about a year and I'm very pleased with it. The price may have gone up but when I bought mine it was only $1.50/sq. ft. compared to around $8.00/sq. ft. for Dynamat. If you want, you can check out my web site to see how it looked when I installed it.
