Second Skin Damplifier Pro Premium Car Sound Deadening Material (2mm) – Butyl Rubber Auto Sound Deadener Mat (13.67 Sq Ft, 8 Sheets) – Made in The USA

Second Skin never a disappoint on material

Rolled down and adhered well to the floorboards on my truck, which is very important. You need a roller to properly install. The black aluminum skin isn't quite as thick as I'd like for resonance dampening compared to an older product I'd previously used on another vehicle, but is no longer on the market. Pricing is reasonable given the superior quality on the product. Overnight delivery was great!

It's second skin!! SMD uses it on the regular. It's a no brainer.

I spent a ridiculous amount of time researching sound deadening materials for our '69 Mach 1 Cobra Jet. There are many brands, including some of the more well-known solutions, on the market. Don't let the "I just received this product and haven't installed it yet, but Amazon wants me to review it so here's 5 stars" reviews fool you into buying an inferior product. If you dig through forums, you find plenty of threads about how someone saved money by cheaping out but the end result looked great. Read deeper and often times you find that the cheaper product eventually failed, or in many cases melted.Simply put, do NOT put any asphalt-based products in your vehicle even if a marketing team claims it is mostly butyl with a hint of asphalt. During my research, I found many sad cases where the asphalt garbage melted and seeped into carpet or body panel seams, making remediation difficult for the owner. I saw one nightmarish photo of someone who used the road-tar stuff on his roof, which melted and dripped out of the headliner. Even less severe cases still had examples of outgassing, leaving behind likely-toxic fumes and odors. Excellent examples of being penny-wise and pound-foolish. Don't. Do. It.Now, for Second Skin... I bought the Damplifier Pro 2mm and Damplifier 1mm for sound deadening in our car during the restoration process. The butyl is extremely tacky but surprisingly easy to work with compared to other brands I have used in the past. The aluminum backing was pliable and ductile enough to conform to any shape we pressed it into. The only negative I encountered is that the printed graphics on the aluminum backing rub off when rolling/pressing tight radii. This has zero effect on function, and nobody will even see it when it is done, but if this bothers you I recommend getting a smaller roller for tight radii.As for heat resistance... I live in the Southern US, and our car is jet black, houses a big block, and has no A/C. Heat resistance was my #1 concern. 450f as a rated temperature is impressive since the VICAT point for most butyl products starts 230f, so maybe Second Skin has some proprietary blend. Regardless, after adhering a sheet to a body panel, I heated the area up to test out how well this stuff holds up. There was ZERO odor and ZERO signs of softening or melting during this test where the panel reached about 210f.Lastly, does the stuff do what it advertises? Yes. While I can't attest to how it sounds on the road yet, simply tapping panels before and after yielded a massive difference. This particular car was a tin can before. A gentle tap to the driver floor pan could be heard ringing through the gas tank for 1-2 seconds. It's almost addicting to knock a knuckle against a panel and hear a solid *THUD* rather than hearing every audible frequency ringing out like someone cranked the reverb to 10 at Guitar Center. At one point my wife said "are you going to keep doing that, or are we going to finish putting this stuff down?" We did roughly 2/3 of the interior surfaces, and the difference is astounding so far. We plan on topping this off with MLV before reinstalling the interior.10/10. Buying more. Highly recommend.

I purchased this product to help absorb mechanical vibration and noise coming from my pellet stove. There are three motors that push air or feed the pellets and when It's going at high speed to keep house warm, it makes a lot of noise.I added strips of the material anywhere inside the stove where two pieces of metal come into contact with each other. I used a sound meter app to monitor the changes. It got a bit quieter as more material was added to the panels and blower motors, but it did not quiet it down as much as I was hoping for.Pros: It helps and is good for high temperature use. Stops bad vibration.Cons: Cost and it can only do so much.

The SecondSkin product is excellent. Thicker and more effective than dynamat extreme but slightly more effective, it works out to about the same price but you are using a slightly superior product. It works a bit better and is a bit heavier, and the adhesive is much easier to work with. The foil is more attractive matte black, and slightly less likely to cut you. I would never buy anything but a butyl based, temperature tolerant thick material with great adhesive, and there are only about three brands that make that- this one is my personal favorite. The rest are all garbage tar products that will fall apart, ruin your car, or poison you. Don't waste your money, if used right you can buy enough of a good brand to cover what is needed.PROPER USAGE NOTE: Since most people still misuse these types of products and cover whole floors etc: THIS IS NOT GOING TO BLOCK NOISE. Try an experiment and place a sheet in front of a speaker- notice it barely blocks any sound at all?! It will lowers noise by eliminating transmission of sound via vibration and resonance of metal and plastic, preventing them from acting like a speaker cone and rebroadcasting sound. THAT is how it lowers noise, not directly. Obviously if you waste your money and put 100% coverage and several layers, that insane weight will eventually block noise but is a nightmare to install, heavy, can cause water trapping inside panels, bad to get to wires or maintenance, massively expensive and just useless. The RIGHT way to use this is cover about 25% of all large sheet metal areas or plastic panels such as inside the outer door skin, the inner door metal, plastic door panel, stock subwoofer boxes, etc. Always treating the center of the panel and working outward for even coverage creates the best result. After 25-35% panel coverage, you already have 90% of the possible benefit and you can literally waste 4x more of the material, money and time to get 10% more. INSTEAD, use this product as intended and add a sound BARRIER like mass loaded vinyl, with foam decoupling layers to block sound, and then add thick melamine foam to absorb sound where needed. I always use about 40 square feet of vibration dampener per a medium sized SUV or hatchback and that gives nice body panel coverage when used strategically on panels like you are supposed to. I then go to mass loaded vinyl and foam with about 60-80 square feet of each.In short, if you want your project to go well and be economical:1) stop vibration with a product like this at 25% coverage. No need to replace decent factory deadening or cover every square inch of everything.2) block noise with mass loaded vinyl with as much unbroken barrier as you can install in doors and floors, and use proper decoupling foam layers so it can hang limp and absorb sound energy.3) add water resistant foams in large cavity or areas like above headliner where you want to absorb mid and high frequency sound that is bouncing around the car.4) buy good materials, you get what you pay for.5) install everything properly, not with simplistic thinking like more is better, etc.If you are on a budget, treat one area first: the doors. You can always add to the project later. A very cheap second project is to simply lay mass loaded vinyl sheets under all your floor mats and trunk or cargo areas. That usually has a decent affect on road noise for minimal cost and effort, but again the large unbroken that barrier is, the better it works.

We applied this to the bottom of our double basin stainless steel kitchen sink. It worked wonders! Dampened at least 75% of the noise. Even the garbage disposal is quieter. Easy to apply.

System sounds alot better now since I've installed the sound deadener
