I used this Dyno-Mat-like sound deadener on the floor boards and behind the seat on my AD. I just put ONE horizontal 6" X Width of door strip via accessing the five-screw bottom access panel. The product has a protective backing that you peel off, the product itself is self-adhesive. What a difference! The 'door echo' has been eliminated completely!

I believe this product comes in 6" and 12" widths, available in the roofing section of big box hardware stores. For 25-30 bucks you can do most of your cab. In fact I believe I read here or elsewhere that 100% coverage is not necessary for sound deadening purposes.

Thanks I have planned on using dyno mat but I didn't know that the big box hardware stors had it. Sounds like a trip to home depot is in order.

I never thought about using Peel & Seal. I had no idea it has acoustic properties. It's made as a flashing sealant around doors & windows. That's a handy bit of info to have.

TRUE "DYNO-MAT" WAS CREATED FOR THE CAR AUDIO GUYS TO GET RID OFF THE RATTLES. I USED IT IN THE DOORS AND FLOOR OF A CAMARO I BUILT. IT WORKED GREAT AS A HEAT AND NOISE BARRIER. HOWEVER HOME DEPOT DOSE NOT SELL IT. YOU NEED TO GO TO A CAR AUDIO STORE OR I KNOW JEGS SELLS IT.

Dyna-Mat is so expensive! I challenge you to do the Coke-Pepsi test between Dyna-Mat and Peel 'n Seal. Those Hot Rod TV shows and car mags. get paid to use those products. I can easily find a use for the couple hundred bucks I saved by using Peel 'n Seal.

Dynamat is quite expensive, as mentioned. I am going to try the Peel-N-Seal on my '66 K10 (BCKNBLK). I actuall kicked around the idea of having it sprayed with Herculiner, Rhino or Line-X, while I have the entire interior out to replace the floor boards, kick panels and inner rocker panels. I believe I will do the Peel-N-Seal instead. For the money and availability, I'll give it a trial run. Thanks for the information.

After experiencing an 80% hearing loss from driving my truck from Colorado to California, I used Dynamat when I stripped and painted it. Sticks real well. Covered everything I could. Inside of the doors as best I could, fire wall, floor all the way back to the fuel tank, over the fuel tank on the back wall under the rear window. Much quieter and cooler. I then installed a big foil covered carpet pad in the floor and firewall area, then installed the carpet kit. Had some Dynamat left over and thought about putting on the underside of the hood although I'm not sure why. I bought it at Al and Eds Audio, a local chain and it was very expensive. If you ask me it's nothing special. Just some kind of tar like substance with a foil backing. I wouldn't hesitate to use some other similar product but I was in a hurry at the time and just wanted to get my project done so I drove to their store and bit the big one. I spayed my bed (dump bed not a wood pickup bed) with a bedliner product. It's a globby paint and doubt it would have much in the way of sound or heat reducing properties. Then agin, I'm pretty new at this stuff...

Cosmo is right. The stuff is inexpensive and works well. I put it in my doors as well as my entire floorboard. You can read more about it if your do a search in the "Interiors" forums. Many have used it.

I used a similar product from my local aluminum supply house. The product was about 4" wide and had a smooth white vinyl surface on the non-stick side. It is used to seal the exterior seams on large, prefabricated aluminum panels that are used for roofs on sun rooms. The 4" stips were easy to maneuver inside of the doors...I tried the 12" stuff from Home Depot....hard to work with and really strong odor.

The vinyl-faced stuff has not peeled in the 100+ temperatures, there is no odor and best of all, it works to take the "ring" out of all sufaces I taped. This includes the overhead and back of cab.

I would highly recommend it and at $13./roll (1-1/2 rolls did everything inside the cab) you can't beat it. Hope this helps!

I bought a 75 ft. roll of roofing ice and water barrier for 35.00 at home depot and did the entire truck, then gave the rest of it to a friend to do his.

I owned a 51 3100 back in the 60s and had a lot of fiberglass bats left over from insulating my house. I stuffed it all under the dash (so hollow back in there), and behind and under the seat. It was amazing how quiet it ran after that. You couldn't even hear those old lifters clattering.

The peel/seal product is intended for aplication to sheet metal duct work in HVAC ( heat/cool) applications and there is no reason it can't be used on or in our old trucks. It is meant to take out the sound of ducting when the blower fan comes on and is used a lot on open roof tops where the AC units are placed. It costs less since it is made in mega quantities. The dynamat is a different polymer which indeed has a sound/vibration attenuation quality and is made in lesser quantities so costs more. It is overkill for most trucks anyway. I say peel and stick away. I have used both. Jon

Well I spent a good portion of the day at Manards, HomeDepot and local Hardware stores
looking for "Peel 'N Stick" not to be found round here. I did find a product by Quick-Fix called "Protecto Wrap" Its 6" wide, 1/16"thick foil on one side, smells like tar and says its made from an asphalt base. Is this the stuff you all are talking bout for sound deadener? I would be a little worried bout the smell, especially on a hot day.
I stopped by a buddy’s house today who worked in the construction trades. He gave me a roll of a product he says, the guys call “Manhole Wrap”. It also is 6” wide, but its thicker, than the HomeDepot suff, its about .110”, it has black plastic backing on one side instead of the foil and it does not smell of tar. It looks like it might be a some sort of rubber product, and it also is sticky on one side, ya peel of the paper and slap it on. It’s used a seal the joints in concrete sewer connections. Anyone ever heard of this product? I think it would work great as a sound deadener.

Wow, these are all great responses. The intent of my original post was to let others know that there are less expensive solutions for common problems. Thanks one and all. Cosmo

Check at a roofing supply house. I used their peel and seal. 12"x33' roll is about $30. Did my whole cab including roof and doors with less than 3 rolls. Great product.

Denny, there are a number of similar products all intended for various apps. The tar will smell forever. The rubber does not on it's own will not stop heat or noise. There are many suppliers of the A/C- Heating trades under a lot of names. Any will work as they are intended to work in an environment that does not allow for odors that would work their way into offices,home, etc. The HVAC products do not or should not smell after initial application. Only the PSA ( pressure sensitive adhesive) should have any solvent that would dissipate in short order. The typical places that sell these are roofing supplier to the trade and of course HVAC suppliers/depts.Jon

I have used peel and seal with no problems. no smell after installing it. covered firewall, entire floor and some strips on back of cab. after this is glued down water heater insulation which was basically bubble wrap with foil on both sides and used foil tape to seal all the seams. all supplies were purchased for $80 from Lowes (no peal n seal at home depot) including the expensive 3m spray adhesive. im in Dallas and have noticed no smell during the summer. this stuff is a cheap option and really makes a difference. but is a real pain to install... i would suggest trying to buy the sound deaden and heat block kits from LMC. p[rice is comparable and the kit is cut to fit. it hink the product was "EVA sound deadener"
