? about DYNAMAT

[Steve1968LS2]

Real popular in the rod market is a stuff like looks like high density jute on one side with a foil layer on the other side.. it is non-adhesive and goes between the floor and the carpet. (about 1 inch thick)..

This would work pretty well in conjuction with a sound "deadener" product like dynamat or simular (since it doesn't absorb sound, only vibration).

69Protour, you have mail

use dynamat or an equivalent like b-quiet extreme on the panels themself to cut down on rattles and vibration from speakers or exhaust. then cover it with jute backing that you can get at a carpet store or home depot i think has it. together this will work well and not cost and arm and a leg. well unless you use dynamat. bquiet is much cheaper. i used this combination on my 96 formula and had very good results. yes i am sure there is stuff out there that is engineered to be better, but do you really want your car to be that quiet inside? the engineered stuff will cost much more as well. the jute will soak up water though. if your getting water in the car id be more worried about how it got there than whether the jute is soaking it up or not. the jute can easily be removed and dried out.

the spray on stuff works good too, but not in aerosole form. youd need to get the spray gun and the gallon bucket of the gunk and spray it on that way. the aerosole stuff simply does not apply the material thick enough to do any good.

also keep in mind that technically you dont need to cover ever inch with the asphault stuff only setions of a flat panel. at least this is what everyone's directions will tell you. so if trying to keep costs down is a priority keep that in mind.

Tom, You've got mail...

Gentlemen, as some know I have been trying to assemble an insulation package for us protouring types. Well I have a couple of products in mind that can effectively insulate, attenuate ( deaden sound) and dampen some vibration. This is 1 product. It is expensive. About 12.00 per square foot. It is proven beyond any reasonable doubt to me. Boeing uses it in some applications. The military also. Is this of any interest to any one? I am still trying to finalize product selections for a kit that is cost conscious, but I had to tell somebody about this one.

[69Rathead]

Sounds interesting, got any links or a product name?

[perry mitchell]

I'm interested. I have been following your links and it all sounds good to me. Tom, please hurry.

Hi guys,
I just wanted to tell your guys that I bought the stuff from Homedepot yesterday. It seemed fairly light and no noticable smell. I haven't gotten the car out in the sun yet.. The best part was that it was $50 for 100 sq. ft.

[Tom Welch]

Bill, are you talking about the pee-n-seel? If so I believe that it will work as good as any branded product that looks similar. The trick is to find the high vibration areas in your particular car. I conducted an experiment with that and Dynamat. The results were very similar. I had no test equipment for this test so I got my co-workers to look at, touch, and try to detect any odor from either product. Once installed both seemed to work alike, no smell either.

Check out this link for a NUPRENE SOUND DEADENER used by BOEING I found on Ebay or you can also do your own searches on google or whatever. I think it is actually made of Neoprene. If anyone has a good cheap source for this stuff or one like it with adhesive backing please don't hesitate for 1 post to help us fellow forum buddies out and let us know...as that is what this forum is all about. I calculate it out to be about $15/sqft at Buy it now price so you know they get it for probably far less than $12 to still make a killing on it. If I find a wholesale source for it I'll certainly post it! But I won't be able to do much searching for a few days so maybe all of us together can find some great sources. Ain't the internet great!!! THX! Link: http://cgi.ebay.com/ebaymotors/ws/eB...974973610&rd=1

[Tom Welch]

I checked the ebay listing for this product, the buy it now price including shipping is 2.07 per sqft. They are selling 15.27 sqft pieces. I havent seen much on this type of sound deadener, yet. I'll contact my secret mole at General Dynamics and see what he says about neoprene. I bet it would work pretty good if properly adhered to the surface it is being applied to. That will be the key.

[69Rathead]

Thanks Tom, sorry about my error...forgot to divide the Sq ft. by price! Makes a huge difference in price! LOL Yes...adhesion would be the key...should not be a problem on the floor but other areas could be an issue...I may end up going with this stuff as it should work well ...at least on the floors. I think I can find out where he gets it from. Boeing has a flight test center at Edwards AFB in the Mojave (High desert) where my brother in law is stationed. He has allot of contacts and may be able to find out or put me in touch with someone. Matter of fact this guy may be working on the base there.

[Tom Welch]

I'd like to see just how this stuff would be used in an aircraft. I have seen no reference anywhere to neoprene being used in an aircraft in mat form. Maybe its used by maintenance crews to avoid slipping on wings, etc. I beleive it is mainly used in gaskets and O-rings. Come to think of it, maybe its a big sheet of gasket material. I would stick with the peel-n-seal. Its cheap, and it works.

[69Rathead]

Could possibly be gasket material...but I kind of doubt it. I work maintenance and have seen similar stuff used inside of equipment to quiet it and as a dark background to allow you to see dropped parts and to help catch them as well. In an aircraft a dropped screw can bring the aircraft down so if maintenance guy drops one he has to let superiors know, file reports, and the aircraft is grounded indefinitely until it is found. I'm sure this is just sound absorbing stuff though. I don't know why you don't just mention what it is you are using. I would be more inclined to support your package and even give helpful feedback on it (as i'm sure other members would too) as that is what this and most forums are for...INFO. Either way someone will find out what it is sooner or later. If you told us and asked us do it your-selfers to give feedback on how it worked you could get allot of feedback and useful info. I'll help you out no problem, as I don't have the interest or the time to try to put something together other than for my own car. If I did "Tuner Jive Mat" would already be on the market! If you are worried about competition...then you might as well save yourself the effort as the sound deadening business is very, very competitive already, if your going to do it, just do it and if the interest is there, it is priced fair, and it works you might make it. I don't have a problem with you trying to put a package together...I support you on it. I would simply prefer to do it myself without a middleman as many of us that are sharing info in this forum do. Plenty of other people will prefer to pay up front a price for your package that has been set up and researched to have good sound deadening products and perform well. You should get your package fully together do a write up on it and post it in the for sale section as that is what that forum is for... also you could set up an Ebay business as well. I think all of us here wether we buy it or not will support your package through recommendations...word of mouth etc. etc. If it works well I'll recommend it! I feel this forum is for the info on Dynamat/sound deadeners... not the advertisement or info that you have a package for sale. If everyone just replied back with an ad for the package they had for sale then this whole website and the forums would just be advertisements for products only which we already get too much of on the internet and in magazines. I come here for sharing info not to read ads. Don't mean to offend anyone I'm just being honest.

Hi 69Rathead,
I hope that you are sucessful with the neoprene. I've not been able to find much on it for vibration control but I guess it would work as well as one of the recognized automotive damper products. The reason I havent provided names of products is because I dont want to be taken to task for a poor performing product. Also most of these are not available to the general public. Just to businesses. I have one of the few remaining full service gas stations in the U.S.. So I have access to several insulation and sound deadener products that are not openly advertised. The acoustical engineer I am corresponding with is working on a couple of products now to finalize the best one for the money spent. By me, or the do it yourselfer. That is once I have decided on the products I will use I will publicize it here. Along with trade names and all other pertinent info. I dont care a bit about competition, thats not why I started this kit stuff in the first place. Its for guys like me who want the best available stuff for the best available price. The products will be available wholesale, too.

[hijack on]

What the hell is a full service gas station? :icon_razz

[/hijack on]

[69Rathead]

What you have going sounds pretty good. Things are much clearer as I understand your position more. I have some other things to do on my car for now so the sound deadening will wait. I'm trying to get it done under $150 when I get to it which is possible but requires a little shopping around...which I have time for. I will probably be doing the sound deadening in about 6 mos so I will keep an eye on what you end up packaging as it may work great for me...just may have to be careful about the areas/amount etc. I put it down on. For example I won't need it for the roof as I plan to use a spray rubberized undercoating for that...don't want anything drooping down as it gets HOT in Phoenix! I'll contact you by PM at that time and see what we can do. Thanks for the honest reply!

[Tom Welch]

So Rathead, are you going to use the neoprene? My research indicates that it or peel-n-seal type stuff will both work pretty good for vibration damping. I have decided to concentrate on sound deadener/blocker and thermal insulation. The vibration damping is easy for anyone to do, just go to Home Depot. The insulation/sound deadener/blocker is a little more complex. Many products offer 1 or the other, some both. But very few offer both in a useable configuration that we can use. I definitely dont want rock wool in my car. Or a foam that is a fire risk. Research continues for the Holy Grail of auto insulation. I know its out there.

[69Rathead]

I don't know for sure...just going to ride it out until I get to that part of project. At that time I'll take a look around and at what weve found (hopefully the "Holy Grail" of sound deadeners by then) and go with something weve found. I don't want to use peel n seal or anything that is Asphalt based as I live in Phoenix and I know that stuff will meltdown in this heat. I agree there is something out there and you should not have to spend crazy prices to deaden sound/vibration.

[ProTeal55]

Just thought I would post my 2cents on this topic.

I used to work in the car stereo business , and we came across which is the best sounds deadinrer product almost every day. Thw winner always came up Dynamat, for overall value and the way the product performed over time.

I just installed some extreme dynamat inside the dash of my 55 Bel-Air , and I can honestly say it is a night and day difference. I have used the fatman product in the past , and was dissapointed with the results.
The dynamat sticks much better to all sorts of surfaces , weather they be clean or not , where the fatman peeled , had a terribile odor , and left a mess behind.

Overall , I would say Dynamat is the winner ! !
