Alternatives to sound absorbing materials?

peal and seal is not a sound absorber.

If you're looking for the padded stuff that cars come with under the carpet it's called "jute" and you can get it in the carpet section at Home Depot.

ohhhh thanks you for that

[quote name='Jaguar']Exo has a few videos on YouTube. My personal experience with Home Depot is that when I went to get some ''Peel and Seal'', they didn't have
anything like it. If your lucky you'll be able to find something at an Ace Hardware center or Lowes. [/B]


Shop Peel & Seal 6" x 25' Mastic Roof Coating at Lowes.com

For the love of everything holy, Jaguar, STOP GIVING OUT ADVICE WHEN YOU DON'T KNOW WHAT THE FUCK YOU ARE TALKING ABOUT! You keep saying that you are here to learn.... wtf, man? I've said it before, and this is a great example... you are going to mess someones car/system/life up with bad advice. Peal n seal will not help anyone who gives 2 shits about their vehicle. Just because some idiot made a youtube vid that says its ok, doesn't make it ok. Please don't use this stuff, op. The aluminum layer is extremely thin, and the adhesive is tar based and smells your car up. If you need a low-buck option for sound deadening get some AudioTechnix b-stock. @cthedinger ;

OP nobody in here knows what they are talking about unless they say Peel & Seal sucks. It doesnt work.

Deadener works in 2 ways. The first is by adding mass to the panel changing the resonant frequency. The second is the rubber based backing (Peel & Seal is Tar Based) absorbs vibrations and expands and converts that energy to heat that it eliminates through the aluminum layer. Tar based products dont do that.

In order to do a proper job 3 products are needed. Deadener to reduce vibrations, closed cell foam to go between panels that rub on each other, and mass loaded vinyl to keep road noise out and the music inside.

When you say sound absorbing materials what are you referring to?

The best products on the market are Second Skin Damplifier Pro and SDS (Sound Deadener Showdown). Both have the price tag to boot. SDS is your one stop shop for all 3 products to do the job right.

Don't go cheap on the ccf. Cheap ccf thins over time and is not worth it. Also on the doors full coverage of deadener is not needed. Buy 80 mil or tiles and do 25-35% coverage and make sure you seal off the holes on the door and you will be solid.

There are some floor underlayment products that would work well. I've used carpet padding and vinyl flooring under factory carpet to reduce road noise. Works well. The padding under the vinyl is just to decouple it from the floor. The vinyl is what provides transmission loss. It is similar to luxury liner pro - mass loaded vinyl with a foam decoupler.

The problem is, he needs it done by Monday, so he needs alternatives. My guess would be he has to have his car put back together by then.

The issue with that though is, for a CLD tile like replacement, there's really nothing out there. You're either gonna need to shell out a TON of cash for Dynamat at Best Buy or your local audio store. Or keep your car in pieces until you can order some product online. AudioTechnix if you just need deadener. If you want a full treatment of CLD, MLV, and CCF, then SoundDeadenerShowdown is the place to go.

If you're just looking to replace the under-carpet padding that came with your vehicle, carpet padding can be found at any old hardware store.

Should have bought everything before he ripped it apart then he wouldnt be using the wrong product for the wrong application.

Most certainly... but it's a little late for that. Hopefully we can convince him to leave it apart for a bit longer and get some proper materials.

Depends on the goal. If road noise reduction is the goal, deadener is not an efficient method for achieving it. Sure, 100% coverage of a good deadener will improve transission loss, but at a high expense in labor and materials. MLV is what is used for transmission loss of the floor and wheel wells both OEM and aftermarket. Given the age of the vehicle, the factory carpet was mostly just carpet. I believe Modern luxery cars are using MLV in the carpet backing.

I will eventually remake my own carpet with standard automotive carpet, MLV, and a jute/rebound decoupling layer. Sound Sense Vibramat is a good example.

The cost of shipping 1lb/sf MLV makes Internet orders less cost effective. You can get fairly dense vinyl flooring remnants in sufficient quantity to cover an entire floor in one or two layers for around $60. Cheapest product that is readily available anywhere.

The only trick with a vinyl layer is that you need full coverage. Any gaps will be sources for noise that reduce the overall effectiveness - like a gap under a door letting noise through.

So. I ended up finding this rubber foam at home depot that goes under hardwood flooring. It is a sound dampening material. I bought the roll and a f*** ton of glue. And laid it out on the bottom of the car. And since we had the seats out. We took the headliner off (only took 5 minutes) and did 1 layer on the hard vinyl headliner. Then put it back on. I did about 2 layers on the bottom of the car. My buddies were sick of smelling glue even though we were outside. And I was just plain tired of the glue on my hands. So we started putting the car back together. Carpets all in. Just gotta jostle it around to get it all to fit right.

Luckily. I didn't have to cut through the firewall like we originally envisioned. We ran the 5 runs of wire (bcuz I already have 1 run coming through a hole in the firewall) through a rubber boot that the steering column goes through. That is also wire the carpeting fits a little funny. But all is good. My back hurts. I spent 11 hours out there.

But its worth it. And will get back at it tomorrow.

Black Jack 100 sq. ft. 28 ft. x 43 in. x 2 mil Roll Laminate and Engineered Wood Flooring Underlayment-70-026 at The Home Depot

thats the stuff we ended up buying.

Oh. And I should add. I wouldn't buy sound deadener for this car because its my winter car. Wisconsin winters are rough and full of about a million pounds of metal rusting salt.

So I would hate to put all that money into sound deadener for a cars body that is already abused by winter.

If it was my summer car. It would be a different story.
