Choosing Sound Deadener

I will say it again, my fatmat has done fine and actually have it in a place where I used to get the most rattles. I also have Second skin in 95% of the trunk. I am going to wait to see how the Fatmat stays when it gets hotter out as I have it verticle right now in those spots I mentioned and if it holds up, will do my doors with it.
Second skin is really good though, but just need to save somewhere.

I have fatmat as well and I think it is good for the price. It has def tamed a lot of the rattles so it is doing the job for me. I don't live in a place where it gets over a 100 often so I was fine with using it.

Sometimes it gets close to 100, but not usually. Our humidty can be a bish though. I live in ohio by the way.

I feel the same, it has quited down my biggest rattle I had. I mean I am sure the SS is helping, but I guess I will have to see. If it don't work, then I will retract my statement, but as of now it is and hopefully will during the hot summer.

There's not much point in going around and around on this. but if you are determined to use asphalt, why not just use Peel & Seal and save even more? All you lose is that goofy blue logo. Beyond that, if you took the $100 dollars you spent on FatMat and bought $100 worth of Damlifier or other butyl mat and covered the same area - just spread out a little, the results would have been as good and you wouldn't have to worry about it.

I hope you don't have any problems with FatMat, or if you do, that it just falls off relatively cleanly. I definitely don't want anybody to have problems but since per dollar spent it is no cheaper and is considerably more failure prone, why risk it?

Just do dynamat extreme right the first time, or second skin. Thats really about it. Very simple.

I mentioned to you before about why it cost me 100 bucks.

Also I spent 140 on the damp, so don't know where you get it I picked it up for 100 or maybe you just were using that as an example, I don't know.

My buddy has peel and seel and his smells a lot more than mine for some reason, but you are right, looks about the same. If I need anymore, I know where to go I guess.

Or Cascade, or if you really want to squeeze the last dollar out of it, RAAMmat.

I was just using that as an example. Because butyl is a much more effective vibration damper, much less of it will do the job of a lot more asphalt. It was a hypothetical comparison - $100 worth of Damplifier (or the other butyl mats) vs $100 worth of Peel & Seal. You'll have many more square feet of Peel & Seal, etc., but $100 worth of either will do roughly the same job. It isn't about square feet, it's about how well the material stops vibration. People argue that asphalt is much less expensive and that is only true when comparing how many square feet you get. Since asphalt has no viscoelastic damping abilities, all you can do is mass load the panel. I know I'm not being completely clear about this, but when people tell me they need to spend as little as possible, I tell them to buy less butyl - same or better end result, no risk.

i realy like the edead from elemental designs they do preety good work its not the best but its abou the same just not as thick i have had mine on the roof 4 layes and it get 120 degress and it stays on never had a proble it dont smell sticks nice only thing is u can get thicker mat but i just double up on the stuff and bam its good id recoment u what has worked for me edead, second skin, dynamat all i recoment and edead is the cheapest by farr then second then dynamat

very true what he says stay away from asphalt all the product ive sugested are butyl or

butyl based

i use dynamat extreme and fat mat in the trunk. put dynamat down first than did fatmat. I also did the floor with fatmat and the doors. doubled the doors and i was happy with it. Its all personal choice honestly. You can talk about this crap for days until you actually try it. I even have secondskin spectrum spray coming in soon. I'm trying everything haha

The only downside to eDead is that it doesn't have a foil layer. That's very important to damping effectiveness. I wouldn't do without it, but there's no question that all of the eDeads, except v1² which has had several reported failures, are going to be more durable than any asphalt product.

Here's the thing with these products. Some are definitely over priced, but none are giving you some miracle value. Butyl is much more expensive than asphalt and foil is much more expensive than the Mylar that eDead uses. You can pay much too much by paying retail, or close to it,. for DX or Cascade, but there isn't any product that gives you Dynamat Xtreme performance for FatMat prices.

Thanks for all the kind words guys.

I think the point that RUDY is trying to drive home is a similar point that we are challenged with quite often.

Customers want to save money. Understandable.

But, unless you know how this stuff works you are kind of shooting in the dark

Comparing the cost of 100 sq feet of Dynamat, Damplifier Pro, or Cascade to the likes of Fatmat, b-quiet and edead, is not comparing apples to apples.

Example.

Weight is a very important factor in vibration damping.

How much does 100 sq feet of Fatmat weight?

Last I checked 100 sq feet weighs about 27 lbs. after the paper was removed.

How much does 100 sq feet of Damplifier Pro weigh?

Our newest batch of Damplifier Pro will weighs .65 lbs per sq foot with out the paper. That is 65 lbs for a 100 foot kit.

Foil is another important factor.

How thick is their foil? 2 mils

How thick is the foil on Damplifier Pro? 5 mils - that is almost 3 times as much foil!!

These factors alone give you much more in your 100 sq foot of material

So when it takes 100 sq feet of Fatmat to get decent results, one can achieve even better results with roughly half as much Damplifier Pro.

Hope that clears things up

Thanks. I think I found my product. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Glad I could help

Let me know if you need anything else.

I am always happy to help whether you use Second Skin or not.

I'd actually expect the same results from considerably less than half. You'd need 2.4 times as much FatMat just to match the mass. Factor in viscoelasticity and the thicker foil and that difference gets even larger. I have no hard numbers but 4:1 would not surprise me at all.
