Guide me please. Sound deadener?
Okay so I have done a search, and am still confused. I even read the very good article that one man tested all the different types of sound deadeners, but that is now dated material. So here is my question. What are you using. I think I have narrowed it down to FAt Mat Rattle trap, and Fat Mat Mega Mat, or Second Skin Dampener. I still don't completely understand the Whole BUtyl thing vs mixed asphalt/Butyl thing. This will be going in the wifes burb with dual dynomax mufflers and a 402 BB. She needs to be able to drive it and conduct business (conference calls and such) and be able to actually hear on the phone. This will eventually be her daily driver so it needs to be similar creature comfort wise to a newer vehicle. I already have A.C. etc, so now we need to get the sounds under control. Right now the carpet isn't in yet and almost have all the door seals installed, but it is an echo chamber for the exhaust and almost gives you a headache when driving around. What are you guys using? How much would I need for a suburban. I figure the whole floor, the roof (under the headliner) the door panels as well as the cargo wall areas. I know this is semi an audio question, but not completely. So moderators if you must move this please feel free to do so, but I would prefer it in this section.
Thanks all! Shawn

Re: Guide me please. Sound deadener?
Me too......used Lizard Skin (sound deadoner) throughout mine. They make both a sound deadoner product and a ceramic product that helps with sound and keeps heat transfer to a minimum.

Re: Guide me please. Sound deadener?
I just bought Dynamat and will be installing it in a week or two. I've heard it's the best. It's pretty dang expensive so it better do something!

I would go with Raam Mat...my buddy used it and loves it. Another option is homemade lizard skin. Basically it is any home exterior latex paint (could use an acrylic), and microspheres you can buy from any aircraft place. |

That is the the article I was referring to. Unfortunately it is outdated. Fat Mat isn't on his list, as are a few other newer ones. I'm especially confused about the butyl vs asphalt/butyl mix dilemma. The lizard skin sounds good, but could potentially be very messy. Is it really as good as laying down a preformed substance with definitive thickness? I don't know, that is why I ask. It seems like the lizard skin would be hard to get a uniform thickness, especially on the inside of the doors. Am I wrong? SHawn

Re: Guide me please. Sound deadener?
I'm using Dynamat , so far I am pleased with it. It is a little pricey though.

I forgot where I was reading but Fat Mat got some poor ratings on another board that I read. I believe it was a link off of HAMB. The homemade lizard skin was on hotrodders. I personally will go with raam mat or this stuff: http://cgi.ebay.com/ebaymotors/ws/eB...3AIT&viewitem= It had some really positive responses on a couple boards. The guy sells it at a lot of swap meets and people buy the hell out of it. It is WAY cheaper than raam mat or dynamat. |

Re: Guide me please. Sound deadener?
Anybody tried the Smittymats yet?
He's plastered his stuff all over ebay as of late for about $2 per sf if I remember correctly. I'd be interested to know... |

Re: Guide me please. Sound deadener?
singer make some called roadkill...i have about 100 sq feet in my truck, works wonders. also use someones lead barrier product. dynamat, cascade audio. that will make the most differance for airborne noise. any style of stick on deadner is really only good for keeping the metal from being twangy.

Re: Guide me please. Sound deadener?
I also vote Raam mat. Installed it over a weekend with wifes help and went really well. (completing it with the wife speaks volumes for its ease of application) I have heard others and Raam mat to me is just as good at 1/2 the price. Bought it direct off the Raam mat website, shipped quick and had questions answered quickly and complete. Gary

Re: Guide me please. Sound deadener?
I used something called "Cool It thermotec" my truck is very quiet inside and I was very surprised, I also used something called "Jute" which we use in our interior shop.

Re: Guide me please. Sound deadener?
THanks for all of the responses so far guys. I really do appreciate it.
I have been reading up on Raam Mat and it looks to be pretty good stuff. I also like the lizard skin idea, but It seems like it would be really messy. I could see it if the burb wasn't already painted, but it is and I would hate to get that stuff all over the place. That stuff that guy is selling on ebay, is it mainly a heat insulator, or sound insulator? I'm looking for a good combo of both, with sound being priority since I can always lay some thermal protection over the top. I am cautious of jute and open cell material due to the fact that the interiors always seem to leek in these trucks. I really don't want the moisture to be retained by the jute or open celled material. After awhile it starts to smell. I think I have figured out that I need a true Butyl Material. Anyone else got any opinions? Shawn

Re: Guide me please. Sound deadener?
I used the Lizard skin all over the interior along with the Second Skin Audio (on floor board only) & am sold on both products. Getting the spray on Lizard skin onto the door skin inboard surfaces was impossible so I put the Second Skin Audio only in doors. Lizard Skin is messy so mask off everything (including shop floor) but is great as a heat blocker

Re: Guide me please. Sound deadener?
Remember, as Al 71 showed, the damperner products are mostly for sound damping, and are not that great for heat insulation, thus you may also want to use the jute or factory insulation for the heat side.

Re: Guide me please. Sound deadener?
Get the best you can afford. The less asphalt, the less likeyly you are to smell it! Butyl 100% may be over kill, but no smell, so it may be worth it. My thoughts are that something is better than nothing, so fat mat will be OK, but I bought the Dyno mat for my Camaro as I plan to run a radical 383 in it and would like to hear myself think, but for the Blazer project, the fatmat will do.

Re: Guide me please. Sound deadener?
A buddy of mine did some testing with "homemade" heat and sound deadening stuff on his 63 chevy II. Here are his results:
Tested different types of insulation for heat reduction. Used an infrared themometer to measure temperature.. The following items were tested: Metal (no insulation) Home-Made Lizard Skin(HMLS) Reflectix Frost King (FK) Peel & Seal (P&S) Results: Metal - 138 deg P&S - 132 deg * HMLS - 129 deg** FK - 121 deg FK, 2 layers - 113 deg Reflectix - 112 deg FK + HMLS - 108 deg Reflectix + HMLS - 101 deg *would not use this on roof, just wanted to see what it did ** only 3 coats, I probably should have done about 6, which I did on the trans tunnel. There is a full write up and really good discussion on the HAMB (Tests start about page 5): http://www.jalopyjournal.com/forum/s...ad.php?t=51399 Last edited by shorty70; 11-05-2008 at 02:32 PM. |

Just stumbled upon this place and thought id share. In the end I did use Smitty but it wasn’t an easy choice. Can see some of it here. http://www.thirdgen.org/techboard/bo...ound-heat.html Just didn’t like the dynamat n others that are just thick heavy tar with a foil backing. The closed cell dense foam made more sense, plus not allot of weight added. I could slap an 1in of tar all over and get the same effects but I didn’t want that. And you can find similar product in the roofing section of any store. But that happens allot, products are marketed in different way and the prices vary on what its for. Like Eastwood, half the stuff they sell can be had at harborfreight for allot less and its the same thing. I stopped falling for that Eastwood stuff; they got a great old name but just resell products anymore. Nearly spent $70 on a bench grinder, till I saw the same one, brand n all at HF for $20 on sale. The powder EW sells for powder coating is the same. They take the same stuff everyone sells, slaps a EW sticker on it and chargers 3 times as much. Pendry and Columbia powder sell the same stuff, but allot cheaper. [ though stay away form eBay powders, they are to cheap.] Lots of folks including me have painted a car with good results with the $40 HF gravity gun, but some say you need a $700 ones. Its all depends . Oops I’m rambling but its always best to shop around. Nice site ya got here. here are the coupon code for Smittys site [not eBay] 10OFF $10 off order of $84 or more 20OFF $20 off orders of $185 or more |

Re: Guide me please. Sound deadener?
I used second skin damplifier pro throughout the entire cab,in the doors,and on the roof,followed by the ceramic brush on heat insulation on the floors and firewall,3coats,followed by the jute material on the floor and tunnel.All damplifier stuff.I've so far only driven the truck down the road in front of the shop,but with a mechanical roller small block,doin a burnout,you can talk at a very reasonable level.It adds a little bit of weight----add a little more nitrous!My .02, I like it.Good luck.
