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 Unfortunately it is outdated.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?
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?
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. |

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?
I ended up going with the RAAMMAT. I spoke to the owner and he was very personable, and sounded honest. I found other message boards he was on and read real life reviews of his product. I even read where some had issues with a batch of his product and continued to read how he remedied the situation and with what type of customer service. Overall I was very impressed. It is the "cheapest", yet quality BUTYL deadener that I could find. I also ordered the closed cell foam to go over the top . I have only added the RAAMMAT to the back walls of the cargo area of the Suburban, but I have already noticed a very big difference. I liked the idea of Second Skin, and Anthony was very nice, (spoke to him more than once), but at the end of the day it was very expensive and I'm not building a competition sound system type vehicle. I also checked into the Butyl Fat Mat, but it was also very expensive, and they didn't offer any closed cell foam. I have some open cell heat insulation (Reflectix)that I'm going to install in the front of the burb area first, then the RAAMMAT, then the closed cell foam. THen of course the carpet. I hope all of this will keep the heat and noise down. We will see.
Shawn
