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.

I used foam and fibreglass carpet pad from menards, glued it in with spray adhesave and it works great for minimal cost. Used it on the floorboards under the carpet too.

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.

| | | | | Joined: Nov 2004 Posts: 1,552 Shop Shark | | Shop Shark Joined: Nov 2004 Posts: 1,552 | 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. | | | | | Joined: Jul 2006 Posts: 482 Shop Shark | | Shop Shark Joined: Jul 2006 Posts: 482 | 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... | | | | | Joined: Sep 2006 Posts: 18 Junior Member | | Junior Member Joined: Sep 2006 Posts: 18 | hi, 3m do a similar sort of thing , sound deadening pads, self adhesive one side,2 foot x 1 foot, warmed up take the shape of whatever you are sticking to, paintable aswell, stick where you want looks like modern factory finish, cheers. [*] | | | | | Joined: Feb 2005 Posts: 531 Shop Shark | | Shop Shark Joined: Feb 2005 Posts: 531 | 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. | | | | | Joined: Oct 2005 Posts: 1,317 Shop Shark | | Shop Shark Joined: Oct 2005 Posts: 1,317 | 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.

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 | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | 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. Denny Graham Sandwich, IL

Did my whole cab including roof and doors with less than 3 rolls. Great product. | | | | | Joined: Sep 2006 Posts: 60 Member | | Member Joined: Sep 2006 Posts: 60 | 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 | | | | | Joined: Jun 2001 Posts: 169 'Bolter | | 'Bolter Joined: Jun 2001 Posts: 169 | This site will give you detailed testing and pricing of most audio and some "box store" materials used in this application. http://www.sounddeadenershowdown.com/ Paul | | | | | Joined: Jul 2005 Posts: 227 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2005 Posts: 227 | 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" | | |
