Opinions-Best cost effective sound deadner - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1970blazin · 10-20-2003, 05:45 PM

I need to put sound deadner in the dash area and under the carpet in my blazer. Maybe in the doors too since we still need to put those together. What is the best stuff, but not too hard to install or too expensive?? Any advice is greatly appreciated. This is our (my husband and me) first restoration, and we are learning as we go.
Thanks-
Diane

Well, something that I used was the anti-skid rubber mats that they usually have in semi trailers to keep the load from sliding. It is a pretty thick type of rubber mat that is also very tough. I have 40 series Flowmasters with headers that exit just in front of the rear wheels and only had thin carpet on the floor (VERY LOUD AT 2500 RPMS) you had to almost yell to talk to the passenger!! Now that I have installed the mat under the carpet and behind the gas tank, I can actually talk in a normal tone of voice and so can the passenger at 2500 RPMS. Best of all was the price it was free because at the factory I got it from they were just going to throw it away. It wasn't hard to install I just had to get my tin snips to cut it because scissors couldn't do it, and just used spray adhesive to keep it in place and duct tape to seal the seams. I really like it, no more ringing ears after long trips!!!!

Check this out http://www.dynamat.com/
The good stuff will cost money

www.sounddeadeningmaterial.com
www.b-quiet.com

B-quiet is a good site because they have a sheet of samples you can order. It's cheap and good to have because it shows you a variety of products and gives an idea what to look for.

*Shane* · 10-20-2003, 06:37 PM

do a search on eBay for "Brown Bread" .... very cost effective and just as good as DynaMat. I say this because I have used both.

Terry Peerson · 10-20-2003, 08:51 PM

You might try to find a web-site for Scosche Industries. I think the catalogue was free. They have a product called Accumat (I think). It comes in three or four different thicknesses. I used three kinds in my 68 VW Beetle restoration. It's awesome! Easy to install, self-adhesive stuff. The stuff I used in the doors was a thin material that is called a vibration dampener. Those VW doors sound like a huge Lincoln door when you close them. It really works!

By the way, if anyone is interested, THE VW IS FOR SALE!!!

i used sound deadener that i got from j.c.whitney worked good and was pretty cheap

jorgensensc · 10-20-2003, 10:23 PM

Not trying to hijack the thread, but what about spray in bedliner. I know some have tried it does anyone know if it works? I'm thinking about doing the same 1970Blazin.

Not sure if it would have great sound deading quality but you would think it would be great for preventing rust on floorboards of the cab.

1970blazin · 10-20-2003, 11:00 PM

My husband put Herculiner in the bed and floorboards of our blazer last weekend. It was mostly to save on the rust and protect the metal. I still want more sound deading, I don't think the bedliner will do the trick totally. Here is a pic of the Herculiner. It was a nice easy job and we POR-15ed the rust before appling the bedliner....

Scott Johnson · 10-20-2003, 11:04 PM

I was thinking about using the spray in bed-liner to coat the bottom of my truck and the inside, then installing the sound proof mats. Don`t know if it would work, but the bed liner should be a good rust preventive and seems like it would help noise slightly.

jorgensensc · 10-20-2003, 11:22 PM

1970bazin, I dig your steering wheel!! what did that come out of?

I use accumat all the time, seems to be the same consistency and stickiness of regular dynamat (not extreme dynamat) but it costs half the money

**N2TRUX** · 10-20-2003, 11:35 PM

I knew an old body man that built street rods for a living. His old cars were as quit as a new car on the inside. He used roofing shingles inside the door's and under the carpet. He cut them to fit, and glued the pieces in place. Then he put the padding and carpet over that. It sounds really ghetto by todays standards, but it worked, and it's cheap....

jorgensensc · 10-20-2003, 11:40 PM

I've heard of that N2TRUX. I thought the shingles ended up smelling in the hot summers?. I also heard they absorb all of the engine and floorboard heat and put it in the cab. Do you know differently?

Hooter · 10-20-2003, 11:57 PM

my friends 73 ford 4x4's floor is covered in shingles to keep the exhaust and water out, they work good for that, and the tar and chicken wire holds up pretty well on the box sides too !!!

jorgensensc · 10-20-2003, 11:59 PM

LMAO!!!!!

All I know is I rode in one of the cars that he built. It as a 36 sedan, and it was like being inside a new car. It was very quiet, and when you closed the doors, they had a solid sound to them.

Look at Dyna-mat. It's not much more than a roofing shingle without the gravel on it. They are all made from dense pliable tar like material.

My guess is some of the new thermal/sound barriers are the market are much more effective though...

1970blazin · 10-21-2003, 10:42 AM

Jorgensonsc- That is the steering wheel that was on it when I bought it. The new LMC catalog has them in it on page 63. It is polished hardwood walnut finish, and brushed stainless steel spokes. They sell for 149.95 new. The blue in the centercap actuallly matches the blue on my blazer perfectly! Feels nice too! (You can also get the steering wheel with a GMC cap instead of a bowtie) Thanks for the compliment!

Also what do you guys think about the thick foam insulation for sound deadner? Will is get moldy if moisture gets in the floorboards??

nate68 · 10-21-2003, 11:17 AM

bedliner and then some kind of insulation on top of that, then carpet.
I am using that aluminum foil and bubble wrap stuff and then some other insulation on top of that or underneath it (i cant remember which) and then carpet.

*rickspickuppart* · 10-21-2003, 11:43 AM

We used that silver lined thermal wraping stuff (3/8 - 1/2" thick sold at outdoor carpet places or maybe home even depot) in a blazer and it worked very good and it is super cheap, I think the 3M spray glue cost as much as the insulation.

go to this web site, page 3240. Has the same thing as dynomat, but industrial intent, (and cheaper).050 thick asphalt sheets. It works great

This is what I have all over my cab. #9709T19 Polymeric Mastic material. .070" thick with a pressure-sensitive backing. Sticks like hell too!http://www.mcmaster.com/catalog/109/html/3240.html#.
Same as Dynamat and FAR,FAR cheaper!
Works great!

tim m · 10-21-2003, 04:24 PM

In the RB Obsolete catalogue they list a spray call cool koat ceramic. It looks like it comes in a 2 gallon bucket. I was wondering if anyone has used it. It is for sound dampening but also for thermal barrier.

BobbyK · 10-22-2003, 12:57 PM

Thick foam could work but be carefull where you put it.Any area that see's any type of heat would prob. melt it.

I used the "Brown Bread" and it's worked great for me.
In your case though, since you already sprayed the bead with the Herculiner I'm not sure how well the stuff would stick on that irreg. surface.
It would prob. work as you have to apply some heat to it when installing it.The heat makes it "mould" to just about any shape.

The price is great,$125.00 for a 70sqft. roll.
I used 1.5 rolles for my Blazer but I covered pretty well EVERYTHING.
