Sure thing! Lets do it in Mexico! ANT Ahhh man I was just in Cancun this year! .... I'll be spending Christmas in Cancun this year. Should be a blast! ANT

Sure thing! Lets do it in Mexico! ANT

Don must be taking a little market share? Probably. But with Second Skin growing 22% last year, it is kind of hard to tell. ANT

Very nice!! Thanks for the kind words! ANT

Thanks guys.. FIxed it ANT

Hmmm... Where does it say that? I thought I changed all the verbiage. ANT

Well... The old Luxury Liner was the 1 lb MLV laminated to the open celled foam. This stuff is 1.25 lbs psf so it is 20% heavier for slightly better results, but you have to add alalye rof OVerkill or Overkill Pro to go along with it so more work is required. Either way, it is good stuff! Very affordable too ANT

We just change our Regular Luxury Liner noise barrier. It used to be a two part composite system made up of 1 lb psf vinyl barrier 1/4" open celled foam We just gave it an overhaul and are now shipping it out. The new Luxury Liner is: 1.25 lbs psf No foam Just raw mass loaded vinyl The price was reduced as well Check it out here: Second Skin Luxury Liner - Mass Loaded Vinyl Noise Barrier - 1.25 lbs psf MLV Thanks for your attention!

Fatmat is one of th eonly products out there I would seriously warn people against. 1. Asphalt 2. soft & thin foil 3. thin adhesive 4. toxic 5. not crosslinked 6, 7 ,8 ... The list keep going... The question was asked how it comepares to Second Skin, so that, I will answer. First, Second Skin is the name of the company, not the name of any product we make, so there needs to be some clarification there. Damplifier Lite is our entry level mat which has a foil that is 50% thicker than the foil on fatmat. The foil is also a higher tempers so it is much stronger than the soft foil they use. Our adhesive is a high grade butyl, is crosslinked, and is non toxic. It won't melt with heat, unlike asphalt. That being said, Damplifier Lite is still an entry level product. Products like our Damplifier, Damplifier Pro, and Dons CLD Tiles listed in this thread would destroyu it in every way. Compare those products to Fatmat, and really there is no reason to take a chance on an inferior product that was originally designed to go on a roof. ANT

I think you might not fully understand the abilities of viscoelastic coatings. In addition to reducing stucture borne noise, they also have a very good mass loading effect. The only issue with them is that a decoupler is not in place, so the results are not as good as a true barrier. These coatings however, will reduce more aiborne noise than constraint layer dampers (when applied at similar thicknesses) . As I stated in my previous post, the difference between the vinyl formulation and the coatings formulation is just a few small changes in resin type (an a couple small addatives) the cured elastomeric coatings are very similar to the vinyl barriers. Barriers however do not exhibit the same viscoelastic nature as the coatings do. Applying a coating on the hood is a great way to pick up extra surface area when you are trying to nail down the last few trouble spots. As you drive, the engine noise travels through your fireswall, in to the cabin. This is where most of the engine noise that we hear comes from. The rest comes either from under the car, or over the car. Some sound waves go through the hood, which then enter through our windshield and ceiling, or under the car through the floor pan. Anythin you put between the source of the noise, and your ears will, to some degree reduce noise. Some things are obviously better than others which is why using the most efficient product for the desired goals is always ideal. That being said, Spectrum is a very cabale vibration damper and to some degree (a larger degree than other products) will reduce airborne noise as well. There is simply no way around this ////M5 I konw you are going to chime in, and try to tear my logic apart. I know your motives. I am sure you want to help people on this forum. I have read your other threads, and though I do not always agree your negative tone and methods, I can appreciate your blunt honesty, and I do know that you know your shit. But please, if you are going to continue to follow me around this forum, and try to evoke a response by talking trash about me, even in threads that I am not posting in, I would encoureage you to stop. No only does it make me feel uncomfortable coming to this forum, ( a forum I am a vendor on) but I am sure you are driving away other members of this forum as well. Several have spoken to me about how you make them feel uncomfortable as well. Don't expect me to jump in to any further debate with you, as I already konw how it will end up. ANT

Actually it, won't. I don't understand why you think it would. Completely different mechanism. Boo, seriously? You don't post for months and then come with this? It most definitely does not ABSORB noise which you seem to be implying and even as a blocker it isn't effective. It should be used for defeating structural resonance and changing damping, but a CLD is better for that. Its sole advantage is in the way that it is applied, but considering you don't need to cover that much of a panel even that is of dubious benefit. I never said anything is absorbed. Those are your words, not mine. Reduced, and absorbed might yield similar audible results in some cases, product to product, but we are talking about vibration reduction through conversion of energy. Spectrum is a viscoelastic damper which converts vibrations in to heat. Just like a a constraint layer damper does. Same principle applies. Since you have a degree in this field, I would expect you to know that the function of the foil is replaced a viscosity is increased passed the point of sheer force.. For example, if we take a CLD mat, like Damplifier Pro, and we remove the foil it will have nearly the same vibration damping power. Now, if we drop the temperature of the butyl to -40 f. then hardness/viscosity increases and the vibration damping results increase back up to a similar point compared to when the foil was applied. The viscoelastic coatings (around room temperature) can be compared to the frozen butyl adhesive without the foil, since the elastomeric value and the mooney hardness measurements are decently close. Thought the products may be different in composition and nature, the results they provide are the same reduction in vibrations through transfer of vibrational energy in to heat. Keep in mind to that the formulation for vinyl barriers is not all that different from acrylic coatings. Resins, plasticizers, mineral filler and 10 other chemicals and additives make each one different, but in the end it is mostly vinyl or acrylic resin, Calcium carbonate or barium sulfate and a few other things. If I increased the amount of plasticizer in Spectrum, and changed out the talc, mica and CC for more barytes, I could make my own non vinyl, acrylic mass loaded barrier. It might not be as flexile but it would be damned close. The weight and density could be easily matched as well. Use enough Spectrum in the wheel wells and you not only reduce the vibrations, but you also start working on airborne noise to a decent degree. Kind of like adding a MLV barrier without the decoupler. Not ideal, but it does work a lot better than loading up on CLD mats, which as you know is hardly worth the money that is required to get those results. The various types of mineral filler in Spectrum, aid a great deal in noise reduction. I stand by what I said earlier. Spectrum is a very powerful tool in when total noise reduction is the goal. Like every tool, it should be used within the realm of its limitations. ANT

Spectrum, is an amazing vibration damper. a viscoelastic vibration damper that will reduce strucure borne noise just as effectivly as a quality CLD mat as long as it is applied at similar thicknesses. As far as using it in wheel wells, it is a great way to reduce structure borne noise closest to the source.. Under the hood it is good for reducing the structure borne noise caused by the engine. Like any sound deeadening project however, vibration damping is only part of the equasion. The other part is the reduction of airborne sound waves. For this, the use of a noise barrier is ideal. I am curious about eggyhustles reulsts. Eggy, how much product did you use? Did you apply it to the sheet metal surrounding the wheel wells or the plastic? Though Spectrum is not the only product that should be used for noise reduction, it is a very powerful tool that will certain aid in noise reduction. ANT

Sound Deadening Materials - Soud Deadening Pads

We never dids come up with a name for the product. I looked through a shit ton of sites and never settled on anything specifically. Still thinking about it.. ANT

Ah.. Sorry guys I actually was wrong about the sizes and just edited my OP. The sizes are med, large and XL ANT

Out of the 2 products you listes, Fatmat & Dynamat Extreme, the Dynamat will do a much better job Here are the differences: Fatmat 2 mil thick foil Asphalt adhesive (will melt, smells foul and is toxic) 45 mils thick Dynamat Extreme 4 Mil thick foil (better constraining from the foil = better damping performance) Butyl Rubber adhesive (high heat rating, better adhesion, will not melt or fall off) 65 mils thick If you are only considering these 2 products the Dynamat extreme, though more expensive, will do much better for you in the short, and long term. You can usually find deals on it on amazon or eBay. $115 for a 36 sq foot box is pretty typicle. If you are open to other products, some good suggestions have been made in this thread. SDS has a great product line Stinger Road kill is great Hushmat is awesome (silver foil, not the black stuff) Ours is solid as well.. Hope that helps ANT

Second Skin is happy to announce that we now have our T-shirts in stock! Sizes range from medium and Large & extra large, and are available in black only Check them out here: http://www.secondskinaudio.com/products/sound-deadener-t-shirt.php Thanks for your attention! ANT

Sounds like you m ay have gotten the wrong box. How many sheets were in it? Awhile ago we printed up a bunch of boxkes with a 28 sq foot count. That was wrong so we had to make a bunch of stickers. We made,12, 20 & 35 sq foot skitckers for each of the boxes. Looks like they might have accedentially placed a 36 when it should have been a 20. Let me know hwo many sheets you have though. Just to make sure you got the right amount ANT

anyone else?

Lots of good info in this thread. Some horse shit as well. When comparing the products Second Skin is very hard to beat. Damplifier compares very well with Dynamat Extreme Both have a 4 mil foil Both weigh .45 lbs per sq foot Both are around 1.5 mm (though DE is slightly thicker our adhesive has a higher rubber content so it weighs a bit more) These are both very solid performers Damplifier Pro is an absolute beast. 6.5 Mil foil 2 mm total adhesive HIgh rubber conten adhesive Our SPLT tiles have the thickest foil in the industry; 10 mils The adhesive has an uber high rubber content a low filler content. Absolute beasts. Just make sure that when you compare our products to anyone elses, you chose the right one to compare against. ANT

getting pretty close to the 5 week mark and son far only a couple of reviews. Anyone else have anything for us? ANT

I am in Phoenix as well and konw some pretty solid installers I could introduce you to ANT 623-533-8193

Out of the options listed I would go with the cascade. Best brand in the mix. Regardless if you use the liquid damper or their CLD mats, the comapny is top notch. Dynamat Extreme would be second, then Stinger. ANT

That is actaully a sample of our SPL tiles. http://www.secondskinaudio.com/products/cld-spl-vibration-damping-tiles.php ANT
