Hot Rod sound deading?

[mad57]

Got a question for past car builders, i see the professional sound deading stuff at shows and man its pricy. The question is will the sound deading stuff for a.c. duct work... work in our hot rods??? The pro stuff is just foiled bubble wrap, the a.c stuff is a dense foam . both are sticky sided. and about the same thickness. I love the (tight) sounding ride from a car thats been treated (wrapped)with the stuff. But would love to save some $. any body ever use the lather?? Thanks ahead of time.

I got a box of Dynomat (9X4sqft=36sqft) off of Ebay for $139. There's a retailer that sells it for that all day long, which I thought was pretty cheap.

I just saw on another forum about "Peel and Seal" from Home Depot or Lowes. It sounds like it is more like dynamat.

Check out "Grace Ice Shield" at Home Depot, Lowes, etc.

 

[Chris Adams]

Yes, the 15 dollar roll at Lowes works about as good as Dynamat for a LOT less.
I’ve used it in several cars, ranging from Tracker to F-150.
Works as well as the brand name stuff, costs a fraction. No odor, even in desert heat. Stays stuck even in trunks. Get a good roller though. A cheap roller will bend on you when you roll the stuff down.

Great for making that stereo sound like it should.
Also helpful if your exhaust is to noisy for comfort.

thanks for the tip guys
I was in need of getting some sound insulation for a project very soon

Will the stuff from Lowes, Home Depot reduce interior heat from the fire wall and floors from exhaust?

-No, Grace Ice Shield is only a plastic sheet covered with tar.

There is also an aluminum sheet product that is covered with tar that may help reflect some infrared radiation from hot parts but it will not help with heat Xfer from hot air.

There is also some aluminum sheet covered with adhesive foam that may help with both radiated and conductive heat.

The stuff I am talking about does nicely. It is a rubberized thick stuff with shiny metal backing. Like Dynamat or the others.
The way it deadens sound is by damping the vibrations (sound is vibration, of course) in the metal. The rubberized stuff works as an insulator, the shiny metal foil side reflects heat, as well as keeping the sticky black part from sticking to your carpet or whatever.

It will NOT substitute for a half inch of asbestos or anything like that, but if you have a 'hot spot' on the floor over the exhaust, common on rods, it can help a lot.
It can also keep temperatures inside. So if you used it on a car and drove it in cold weather, it would be warmer inside, although I doubt it would have a really high R-factor…

I used Peal and Seal on the back wall of my truck's cab and it worked out nice. I put 2 layers and it made quite a difference. I don't have a decibel # or anything but it was noticable. IMO worth the $30 I spent.

I got a J roller from Harbor Freight and it worked out well. Better built than the ones Lowe's had and I paid maybe $10 vs $30something at Lowe's.

 

[Crusty Nut]

Yep, go to your local roofing supply and get some "peel and seal". Some sources say it is the EXACT product as eDead and others on the market, just substantially less money.

 

[metal1313]

peel and seal really is pretty much identical to dynomat. hd usually only has the 6-8in wide rolls but you can usually get the wider rolls at roofing supply houses for pretty cheap. i've done a few of my cars and my truck with it. it makes a difference, espically on my mom's focus. in my bronco ive done every where, including in the doors, on the roof and several layers on the floor. i bought it in 24" wide rolls and then a few of the narrow ones. with a good roller it goes down quick and easy. and it sticks well, my bronco is herculined inside to help water/rust proof it and it stuck fine

To all- thanks for the great info. I need to quiet my diesel truck down some on the inside. I have a question about the install. When you install this stuff say on the doors. Do you install on the inside of the door skin or on the inside of the door panel or both? I don't have a clue as to where to start. Doors, floor or the roof.

I can give you some ideas, but you can search Google for great pictures, videos, etc. Search under Dynamat or any of the twenty name brands.


On doors you do the inside of the outer skin. Means working in the little holes in the inner door wall.
Under the carpet means you have to be careful you don't rip your factory carpet, which is WAY easy.

Under seats helps a lot. Along the back of the cab may make most the difference. Under the front kick panels is also good.

On my F150 I pulled the carpet, and the back panel and covered all of that. Inside the doors I covered the skin and put other material under the plastic door panels.
You can't see anything with the eye looking in the truck but it is VERY quiet on the road. Still get some pipe noise but that mostly comes through the window glass.
Makes the sound system much nicer.

Downside, I don't hear sirens, like fire trucks, until they are fairly close.
Noise level in a lightly modified (tuner, intake, exhaust) F150 is about the same as a stock Cadillac.

Peel n stick works good for floors and horizontal surfaces, but I would not use it on vertical surfaces because just like Edead it's been known to peel away even when using a heat gun to apply it. It's not good when a piece comes off the inner door skin and gums up you window and hardware. There is a product I recommend called Raamatt. It has an incredibly strong initial grab and holds like you would not believe. I never even worry about using a heat gun when applying it because the bond is so strong. So strong in fact, it takes a careful hand to apply it. It is alot cheaper than Dynamat Xtreme and is a much better product.

 

[mad57]

Wow guys lots of first hand info here thanks again,mike.

 

[nate379]

I did the back wall of my truck last spring and it's been fine. I was told the same, but it has survived 115* Idaho summers and -40* Alaska winters.

I've read numerous accounts of peel n stick making their vehicle's interior smell like tar for months. Some experience it and others don't. It eventually goes away but depends on what you are after I guess. Also keep in mind these are tar/asphalt based, and during a hot day it can seep out onto your panels. Good luck cleaning that off if you ever have to remove it.

It appears the link I had above has been changed from the last time I read it. It gave a pretty good comprehensive test and review of many different products including Dynamat and peel n stick.

If you are on a tight budget, then go with the peel n stick but expect it to fall off any vertical panels or the roof. If you want something better but still not kill the budget, look at raamatt or even lizardskin/second skin. The benefit with lizardskin is that it doesn't add a whole lot of weight to the vehicle, if that is a concern. One can add a few hundred pounds to the vehicle real quick using asphalt based soundproofing. IMO there is definitely a difference between boxstore quality peel n stick and quality deadeners. Read up on asphalt vs. butyl based deadeners and you will see what I mean. Another interesting read, which ironically is the person who created the sounddeadener website: http://www.stevemeadedesigns.com/board/index.php?showtopic=20533

The stuff I posted about is not 'tar paper' it is a rubber substance. It has no odor stronger than that of its packaging. I don't smoke, don't even eat in my F150. I can smell the leather, smell the wax on the door sills. No smell from the stick on stuff.
It has been stuck to the rear wall, up and down, and the inside of the door skins here in the California Desert for two years.
No odor, no falling down.
I have only seen asphalt based soundproofing from the name brand makers.
We have had fairly cool years, but it does get way over 100, a lot. Inside temps hit 135-140.
It's also in the trunk of one of the cars, no odor from trunk and that car is parked in the sun seven days a week.
All my cars are kept closed, well, except for the open cars, you don't drive around with the windows open here, summer way too hot, winter too cold and windy.
So you really notice any smells. Really.
When I used the wrong silicon in one car it was horrible. Had to open the car for weeks to get rid of the odor. That was from about a thimble full of GE silicon behind a headliner.
If there was any odor from the deadener you couldn't drive the cars.

What about aresol rubberized undercoating? I would think that would dampen vibrations in the panels. It is cheap and easy to find and easy to apply. Just a thought.

We tried that. It 'outgasses' or stinks to high heaven. Used it on a hot rod, open car. After a couple months it was OK.
Very, very messy. Like you would not believe.
And cost a lot.
We used the Westleys (sp) brand.

Like I said, some people experience the smell and some don't. I'm in the Mustang arena and it is a common complaint with "Peel n Seal" or "Peel n Stick" from the local box stores. A google search for Peel n Seal and smell will give mixed results, some complaining about the smell for months and some saying it doesn't smell. It also will show people complaining about it not sticking after a few months installed (DIY and professional installs), while others say it's been on for a few years and hasn't moved.

By the way, Peel n Seal/Stick is definitely asphalt based and is intended for weatherproofing horizontal roofs, not automotive sound deadening. It just happens to be similar to automotive sound deadening and is cheap.

From their website:
Peel-N-Seal is a 40 mil. thick waterproofing membrane consisting of a self-adhering rubberized asphalt laminated to a high density polyethylene film. A special release liner prevents the membrane from sticking to itself in the roll. The heavy polyethylene film is resistant to cuts and tears while providing excellent waterproofing characteristics.

Also: http://bma-sales.com/pdf/peel-n-stick.pdf


To minimize an argument, yes it works and yes people have gotten good results with it. It is thinner than the products made for soundproofing and doesn't sound proof as good as the thicker stuff. Ultimately there are better alternatives to peel n stick, but it all comes down to the budget and what your goals are

This guy has some of the best stuff out there. its cheaper and lighter than some of the other options. And butyl based, not tar/ashault, so there is no smell. A lot of guys use this on performance applications where they want to deaden a bit of the sound but dont want to add lots of weight. I used a layer of the RAAMat BXT and a layer of Ensolite foam in my car. Addeed about 30lbs, but did a LOT for the sound. And is MUCH cheaper than some of the other options.

Personally a fan of second skin. I used it in my diesel F-350 and it helped a lot. Fairly easy to apply also.

I have actually posted about the smell from the tar paper stuff myself, so I suspect you hit my posts from 2004 in your search, along with others, of course.

By the way, I didn't post about 'peal and stick'. They don't carry it locally.
Others did post about it, including some pictures. Don’t know anything about it, looks like tar paper but again, never used it myself.

The stuff I posted about has the metal backing on rubber. Not on the website you linked.


We are talking about different products here.

I have had customers complain about the smell from Dynomat, back in the day we sold it. There are lots of different brands, types, versions, etc.
I think there are maybe 100 varieties of sticky stuff floating around right now.
Got to be confusing.
Some person uses item A, forgets and thinks he used part B, and posts about it, reader thinks he means item C which is what is available at his store, or what was originally posted about, then everything gets even more confused.

Agreed, I use RAAMat BXT in my cars with ensolite foam. cant beat it for the price, and the service is great

Thanks gte719P that is what I wanted to hear. I am trying to deaden the noise in my F350 as well.

I've been very pleased with cost & performance of Rammat & ensolite.
