I am replacing my carpet and am wondering what that silver stuff you guys are putting down is. I went to Oreilly and got some silver stuff for under the carpet, but it has insulation on one side. The stuff you guys have looks as though it forms or is sticky. Also, where do I get it? Thanks.

im going to piggy back off this and ask anyones opinion on whether or not the insulation is worth it.

do you see a large reduction in noise?

I don't know the answer but will be watching the answers closely.

Thinking of replacing my carpet soon. :)

Theres the factory stuff which is ok then theres dynamat hushmat and many other brands and yes any sound deading will kill noise in the car.Many of my friends do car audio and swear the stick down like dynamat lined the whole trunk the car don't buzz and rattle like most you hear going by blasting music.

I don"t know what it is called,but the from what I know both in car audio and general car knowledge I have, It is well worth the time and effort. Even the insulation thatused tohang from your hood helps reduce heat and noise.you may want to make sure it does not retain moisture.
Just be careful not to put stuff in that is too thick it may be hard to re-install the seats and shifter plate etc...

A good example would be to take a ride in a 1969 dodge power wagon (no insulation) if you can still hear,then take a ride in a 2008 cadillac (insulation)

I just installed Rattle Trap in my car... it was about $200 for 150sqft of 80mil stuff... it took one of tworoll to do the entire trunk and behind the rear quarter panels doubling up on the wheel wells. It will be a long time though before i get to try it out. but i still have 1 roll for the front of the vehicle, doors, and roof. i can post some pics but i cant tell you about the effectiveness of the product

The stuff I found I'll be using does more than cut out sound it also reduces the heat in the car.

Very similar to dynamat and this comes pre-cut for year specific models.

I used a product called FatMat. I purchased 100 square feet and split it with my cousin. We did both our Mustangs. I would have liked to have a bit more to line my doors. I think it was around $120 shipped. It is very similiar to Dynamat and goes on very easy. It did quiet down the interior. Here is a picture of it installed.

I love you're paint-matched shift-knob :-]

I used some heat insulation from Dixiline lumber this past weekend.. I dont think its going to last very long though.. It was a sandwich of aluminum, bubble wrap, and more aluminum,, it really cut down the heat and with the extra carpet on top the noise came down too.. But I only did the cabin floor, Its a hell of a lot better than the bare floor that I had before..

fixed

Thanks true66gt. I tried to figure out what the problem was, couldn't, and just gave up and left it the way it was. I don't do a great deal of posting. sorry

Well... I could be wrong but...
I look at sound and heat deadening products differently from carpet underlayment. Yes I know the underlay helps in this area but I look at it as more of a cushion floor to make the carpets softer:D

Our car is getting something like the following...
POR-15ed (http://www.por15.com/) - top of firewall right back into the trunk.
3M Seam Sealer (http://solutions.3m.com/wps/portal/3M/en_US/3MAutomotive/Aftermarket/Products/New-Products/?PC_7_RJH9U5230GE3E02LECFTDQCEA7_nid=GS5YCJFDF4gsQ H8HT14PGTgl9292JMRLJTbl) - brushed on over all the joints and seams.
Dupli-Color Bedliner (http://www.duplicolor.com/products/truckbed.html) - 2 coats over POR-15.
Damplifier Pro (http://www.secondskinaudio.com/vibration-mat/damplifier-pro.php) - firewall, floors, roof, trunk, trunk divider, rear wheelwells, quarter & fender panels.
Spectrum (http://www.secondskinaudio.com/sound-deadener/spectrum.php) - Over all the Damplifier Pro and possibly on the undercarriage.
Dupli-Color Bedliner (http://www.duplicolor.com/products/truckbed.html) - 2 coats over Spectrum.
Original style Jute Underlayment - front & rear floors, tunnel and firewall
Toped off with new Carpet.

Overkill? ehh who knows! Should be quiet though and thats what she wants. As all you married guys know.. she typically gets what she wants! :D

and the best part... that'll add at least 200lbs to your car

^^^^^^^^^^^^X2!!!!!^^^^^^^^^^^^^^

That is way overkill and will just add weight. Spectrum is an undercoating so there is no need for bedliner on top of it, that is just extra weight. You should put the spectrum on the underside of the car and just do away with all the bedliner, spectrum is designed to perform on the exterior. You should also put some luxiery liner in, that will help with noise a lot.

For anyone considering sound deadening, I strongly suggest NOT getting Dynamat. That stuff is so overpriced its rediculous. What is it?, 245$ for 36sqft?

I did 100sqft of Fatmat, and it came with a handy little roller and knife, for about 80$ shipped. Then I adhered Tekfoil to the roof and firewall to greatly reduce heat. It's the same as that shiny stuff old people put under their windshield to keep the sun out.

Alltogether I spent about 100$ and only added around 30lb. Tekfoil is near weightless.

good price and great product, best part it is not asphalt based!

are you pleased with the results?

i have a 67 daily driver that is all orignial and im considering this addition to help make the drive more bearable.

I highly recommend RAAMmat over FATMAT since FATMAT is asphalt based and RAAMmat is butyl

For any who are interested, RAAMaudio is selling rolls of RAAMmat on ebay for $80 plus shipping. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=016&sspagename=STRK%3AME WA%3AIT&viewitem=&item=260237895489&rd=1
There was a problem in production so they are offering it cheaper, read the auction or RAAMaudio's webpage to learn more.

The car is not road worthy right now so I cant truely tell you the results, but I garuntee you noise will be greatly reduced. 100sqft was enough to do all the cabin and double many places up (wheel wells, transmission tunnel, roof above driver seat,etc). I did part of the trunk too, but then found it unnecessary becuase I instead made a rear seat divider and sealed the cabin from the trunk well. I figured the trunk can be as loud as it likes, as long as I cant hear it.

^^^^thank you i appreciate your response.

now you used fat mat for the floor and then tekfoil for everything else?

and if you dont mind me asking how long did it take to do all this? is this a weekend job or is this more like a spring break/winter break/summer job.

Fatmat is not asphalt, it is just like raammat (butyl) but it is cheaper. I havent compared thickness between those two, but even is RM is thicker, it wouldn't compensate the price...

Here Hot70, I posted pictures of my progress back in January. They seem to be usefull in showing how much you can actually cover with 50sqft and 100sqft. I don't believe they show the Tekfoil, I'll have to find separate pictures of them....

Actually.. FatMat IS asphalt (rubberized) based... Read 1/2 way down page (http://www.sounddeadenershowdown.com/products/).

I ran out of Fatmat for the firewall, so I bought some PeelnSeal to put on it, then the Tekfoil, then some new OEM style that I had laying around anyways. Come out real nice IMO

thanks i found this very helpful. how air tight does the foil have to be? it looks very taught over the floor. was this very hard to achieve such a tight fit or is it somewhat average skill level to put in.

It came with a little wooden roller that flattens it all out. The more I worked with it the quicker and better I got at laying it down smooth..

If your doing the floor, its not that important to have it all flat and stuff, but if you do vertical or completly upside down, you HAVE to roll it nice and flat. Actually, I'd highly suggest using a heat gun when doing vertical or upside down. It makes it extra sticky...

Not quite, perhaps 100 but I see 1 person driving it 85% of the time alone and the other 15% only 1 passenger (me). Also there really isn't that much weight being added. The Bedliner weighs almost nothing so a few light coats is fine. The biggest "extra" thing I'm adding is the Spectrum. Other than that its not much more then people who POR15, Seam Seal, Prime, Paint Sound/Heat Deadener, Carpet.

You should also put some luxiery liner in, that will help with noise a lot.


While Spectrum is an undercoating it can still be used inside the car and is actually recommended to do so by Second Skin. From their website (http://www.secondskinaudio.com/sound-deadener/spectrum.php): "When applied to the interior and exterior floor pan, Spectrum can reduce 300% more road, engine and exhaust noise than traditional OEM dampers and tar boards, all at half the weight." I've called and asked them a number of questions and using the Spectrum in this manor will provide a really quite ride.

As for the bedliner.. as above its really only light coats which does not weigh that much. The fact that I was given 2 cases of the spray cans compels me to use somewhere. :D I guess I could go without it on the POR-15 however I'd prefer to have bedliner/paint over the Spectrum. Regarding the Luxury Liner product I was looking at that and would replace the underlayment with it if I were to use it.

i know you can use spectrum inside and out, i thought you were going to use the bed liner just to protect it on the outside and that is not necessary. If you are given a couple cases of bed liner then you might as well use it, i i had a bunch for free i would find some place to use it also. If you do the whole car you will add 100lbs just in damplifer, the weight adds up fast but so does the sound dampening. I highly recommend luxury liner, i bought some and it is great stuff, a lot like what is used in the luxury vehicles today.

For anyone who doesn't believe me to be a creditable source I put a lot of time into research when i was trying to kill the drone in my grandprix and what i am sharing is some of what i learned along the way. Second skin makes some good products. My mustang will be getting a coating of spectrum in the tranny tunnel when i have the tranny out, the rest of the bottom will get it after i replace the floorboards. RAAMmat will go inside and that will be covered in luxury liner.



FATMAT IS asphalt based, not butyl unless they just changed it. If that is the case please let me know. I highly recommend reading the first link i posted for anyone who is thinking about doing sound dampening. It is a unbiased study on the different brands.

I guess I really started something! Can I get any of this stuff at the local auto parts guys? Thanks

Hmmm, well, I might be wrong then I guess. I looked on their website and it says "rubberized compound", but the place I bought it says butyl. Either way, I still like it...

Another cheap(ish) option is eDead. I alsoknow a 15% off code that makes it nicer...

a place that sells lots of car audio equipment would be your best place to buy it local

It's going to depend on what products you use. Your likely best off to simply buy it online from whichever company. If you have questions just call them, if there is a problem just call them. Not gonna get that from most parts shops who will likely charge more and taxes.

Yes.. I read that "rubberized compound" comment on their website. Hmm.. The word compound is much nicer than asphault isn't it? I really hate when a company does this crap to sell their products. This and the fact that the place you bought it from lied about its makeup would tick me off. If it were truly a butyl product you can be sure it would be stated on their website.. which it isn't.

For anyone interested in the Second Skin products sign up over at their forums and make a few posts. When you purchase from them directly call them and let them know. Its worth 20% off your order! :D

anthony(the owner of secondskin) told me they stopped doing the discount and just lowered all their prices to make up for it. If you got this recently let me know, i will most likely be placing an order this summer. You can get 10% off if you load up your shopping cart and do all the the steps to complete the order BUT do not submit the order. Go to bed and when you wake up in the morning you will have an e-mail with a 10% off code. Well that is what happened to me 6 months ago, i just wanted to see what shipping was going to cost.

Secondskin is great to work with. When i ordered 2 gallons of spectrum for some reason only 1 gallon came even though the order showed 2 were shipped and the weight was 20lb's according to the box(1 gallon weighs 10lbs). The weird thing was that the size of the box would only allow for 1 gallon to be shipped. I called up second skin and they had another gallon coming to me that same day, no questions asked. I was very impressed.

a few days ago i went with a friend to an audio store for him to look at stuff for his car. after listening to the salesman go on and on about dynamat, I wish I would have done it on my entire interior. It will keep sound out, help with vibration, and greatly improve the sound quality of your audio system. Dynamat is expensive so I would look in to fatmat or some off brand cuz it will prolly do the same thing.

well i still have the 'underlayment kit' that came on these things stock, so its not too terrible. You can definitely hear and feel the road and engine. And at idle the whole car vibrates (combo of my crappy engine, and possibly the lack of dynamat). I would go with one of the aftermarket products if I were to do it again.

Dynamat isn't expensive, it's ungodly expensive haha. I just checked out their website and 72sqft of Dynamat Extreme is $540!!!

ya.... go with an off brand of dynamat. fatmat or whatever... something cheaper.

snorulz.. ahh ok. I got that info from an audio shop here. The guy I was talking to said he ordered a couple years ago. So yeah that may have changed.

ninteen66mustang.. Dynamat is ungodly expensive (as baddog671 so put) and is not the quoted best stuff out there.. its good but not the best. Also Dynamat (Butyl based) and FatMat (Asphalt based) are complete different makeups. If your looking for the Butyl I'd suggest the Second Skin products like Damplifier Pro. It is still expensive but overall better than the Asphalt based products. If your looking to save and go with Asphalt then I'd suggest FatMat or B-Quiet Ultimate.

I'm not putting down products like FatMat as many people here have used them and are very happy. Its just that the Butyl products do perform better.

I'd love to see results from the same tests over at Sound Deadener Showdown (http://www.sounddeadenershowdown.com/) done in a more scientific lab from an independent source. Add to the tests would be an audio test to see what the sound dampening difference are as well.

RAAMmat BXT is butyl

hey baddog, whats the thickness difference between fatmat and peelnseal? cause in all pictures the peelnseal looks the same thickness as fatmat

but according to this (http://www.sounddeadenershowdown.com/products/), it looks to me like peelnseal is about the same as the bquiet ultimate. which is pretty thick.

I think you guys are way over thinking this. Everyone talks about butyl being better than ashphalt product, but is the cost difference worth it? Or, is it a marketing ploy. Anything laying on the floor, covered by carpet, isn't going anywhere. Vertical adhesion is not a big issue, unless you're worried about the firewall. If that's the case, use something different on the vertical surfaces.

I've had eDead in my car for 2 years and have had no issues with adhesion on the firewhatsoever.

http://www.midnightdsigns.com/Mustang/Insulation/Insulation%20001.jpg

im willing to bet that edead is the exact same stuff as peelnseal. except peelnseal comes in a narrower roll.

Probably, its pretty much all the exact same thing...eDead would be cheaper than PeelnSeal though
