Review of:Sound deadener

There is a lot of good info on here, but not much in the way of actual results. So here is the products that I have ran Dynamat Original, Dynamat extreme, Edead, Fatmat, Fatmat Xtreame, Fatmat Rattle trap XXX, Zilla mat, B-Quite, hushmat, and now Second Skin.

Dynamat original is good but you have to it to get it to stick, but once in place it is good to go. I would not use this on roofs, or trunk lids, or doors, just on you floors. No mess at all with this stuff.

Dynamat Extreme works great can be installed any temp sticks great. This stuff can be messy while installing, and will cut you up pretty good since the metal backing is so thin.

Edead do not recommend this stuff is asphalt needs to be heated up to stick, and falls when it gets above 100 degrees outside. This stuff can be messy while installing. This stuff can be messy while installing.

Fatmat do not recommend this stuff is asphalt needs to be heated up to stick, and falls when it gets above 100 degrees outside. This stuff can be messy while installing. This stuff can be messy while installing. This is the same stuff as Edead, maybe a little bit better quality in the foil, but that is it.

Fatmat rattletrap XXX is ok but still do not recommend this. You will have to heat this up to get it to stick good, as it is half butyl and half asphalt. But, it holds up in 100 degree temp outside. But if it is above 100 degrees outside for long periods like 12 hours in the sun, it will start to sag in places. This stuff can be messy while installing.

Fatmat Mega Mat works great can be installed in any temp. Sticks like a SOB. It is almost impossible to get it off when it is stuck to metal, and forget it if you stick it to its self.

Zilla mat do not recommend this stuff is asphalt needs to be heated up to stick, and falls when it gets above 100 degrees outside. This stuff can be messy while installing. This stuff can be messy while installing. This is the same stuff as Edead, someone told me that is the same company just a different name used on packaging.

B-Quite is ok but still do not recommend this. It is almost the exact same thing as Fatmat rattletrap XXX. You will have to heat this up to get it to stick good, as it is half butyl and half asphalt. But, it holds up in 100 degree temp outside. But if it is above 100 degrees outside for long periods like 12 hours in the sun, it will start to sag in places. This stuff can be messy while installing.

Hushmat is good can be applied at any temp. Unlike most companies that bounce the sound back at you and can help gain you DBs on the microphone. This one does not increase your sound it actually absorbs sound. This stuff can be messy while installing.

Second Skin works great and can be installed at any temp. This stuff sticks just as good as, if not better then the Fatmat extreme. The nice thing about this stuff is that it has easy clean up and no mess left behind. Plus it is thicker than any of the other mats that I have mentioned. In comparison to Dynamat it is about 1.5 times thicker, so 2 layers of this is like 3 layers of Dynamat.

IMO, I would have to say that Second Skin takes the cake when it comes to sound damping material, for all bang for your dollar. I would have to say that Fatmat Mega Mat is in close second, with Dynamat Extreme tied for second, and in forth would be Dynamat original but only if used on floors. As for the rest mentioned please donít waste your money to save a buck or two. Spend a little more and get something that works good the first time around. I know that there is a few that have not been mentioned, but I have not personally tried them. Right now I will only be using Second Skin in all future installs, as well as cars I do for someone else. I am tired of helping someone put in cheap product and to have them come back a month later saying I did something wrong, because it is now sagging down.

Not a bad thread and your right, it can be hard to find good info on here about various deadeners

FYI Edead is butyl based. Pre 2010 it was asphalt. Nonetheless it still does not stick worth a darn.

Nice thread, thanks. I actually have some Rattle Trap right now. :( I am happy it is not on my roof, but assume that after so long it will fall off my trunk lid. Welp, gotta get some new stuff.

What do you guys think of liquid deadener? Such as second skin spectrum and spectrum sludge / etc?

How effective? Price/performance? Only use in nooks and crannies, or coat trunk with it? Etc

my fatmat never loosens or nothing. and i have no ashpalt smell. it was completely rubber based. its been over 100 degrees where it sits and never comes undone or nothing. and it wasnt a pain or need to be heated to be installed

Same here. Last week it was about 100F in my car for a few days and none of my Fatmat fell off. I just made sure that I wiped down all my surfaces with rubbing alcohol. Maybe the older stuff was asphalt based and the newer is butyl? It may not work the best but it was inexpensive and it helps.

Ok you guys might own the Fatmat Mega Mat works great can be installed in any temp. Sticks like a SOB. It is almost impossible to get it off when it is stuck to metal, and forget it if you stick it to its self. That stuff is butyl. There is 3 different levels they sell.

its cheaper to double up on it than it is to get enough to do a single layer of it of most other stuff

also the secondskin is not thicker then rattle trap.. i have both in my truck now and LOTS of each.. however the secondskin is stiffer and does what i need it to do better and the flat black looks better imo then the chrome type foil... I have rattle trap and damp pro

just curious but no where in this thread is a testing format. seems like the only thing you are basing your review on is how good the mat sticks to a surface, not an actual way of testing dampening effect. the reason I bring this up is b/c I made something that I'd like to actually test against these products but it seems there are no definitive test that show how or what makes one better than another. I've seen points that Sound deadener showdown have made that ensure effectiveness and some of what make a product more effective. if anyone knows how to actually make a fair test for these products I'd love to put my product in that test. the difference with my product is that it would actually need to be applied with a contact cement or spray adhesive like 3M Super 77.

like what kind of work? I am very curious about this b/c all these sound deadener companies claim there product is the best but there is no actual test format to prove one is any better than another or how one is different from another. I'm just tired of hearing that "company A is junk b/c I don't have the tools to apply it correctly" when the truth may be that it may actually be a superior product. the only test I've ever seen is the oven test at 400˚F for whatever amount of hours, this test I find is useless b/c I've never seen any part of a car reach 400˚ except for the exhaust. I've also see the bell test, when you put a piece on a bell to show how it doesn't resonate, again another useless test b/c you can put duct tape on the bell and it'll do the same thing.

You forgot Sound Deadener Showdown and Raamat :)

How do I know if my eDead is pre-2010 (asphalt)? Seems to stick OK with a roller...

You can get sound deadener acoustically tested. I have had my deadener acoustically tested using the SAE J1637 style testing. I also have paid to get Second Skin Damp acoustically tested. I hope in the future I will be able to get several other deadeners acoustically tested since most companies do not actually get there product acoustically tested, or if they do they do not post the results they got. The problem is it is expensive to get this testing done.

i was going to say... Deadeners purpose is to change the resonating frequencies of the panels applied to.. would need to apply and be able to test the freq. Which getting the exact same amt of mat everytime would be tough.. would be easy to do rough tests but to be very very precise i doubt anyone on this forum is capable. You need a lab.. lol.. but as far as this forum goes like the guy posted.. the best way is just someone who has knowledge and has used many diff brands in many different cars and can give their educated opinion

where can one go about getting one of these test? about how much does it cost? how big of a sample do they need?

There are several different labs in the U.S. that do it. It can be anywhere from $600-$1000 per sample depending on where you get them done. They only need 2 or so sq ft.

oh oh let me let me send mine in... lol.. this might as well be worthless info..no one is doing that... for 600$ you could buy ANY brand of deadener and have your **** like a rock
