Second Skin Damplifier Pro Butyl Rubber Sound Deadening Mat (2mm) - 12” x 10” CLD Tiles for Car Sound Deadening (15 Sq Ft, 18 Tiles) - Made in USA

Works well. Reduced noise at least 65-75%.

Very high quality sound deadner. The glue they use on their sound deadner. I found to be much stronger then other sound deadners. Definitely recommend this product! Worth every penny and works wonders.

There is nothing else to say. Second Skin Damplifier and Damplifier pro is the best damping material out there. I know there are cheaper options out there, but there is a reason why this is always used in pro builds. I've used Dynamat, Stinger Roadkill, NVX, Murdermatt, and this is by far my favorite. I haven't ever used any of the really cheap ones on here because they normally come with a very potent smell, and I think Dynamat stinks, this has a scent, but its far from a smell. Installed in late August, yes I've had it in the car in heat, so I can atest it doesn't smell in hot. Working with this stuff is a dream. Very, very rigid compared to road kill and Dynamat which is very floppy, makes this stuff very cooperative. It cuts easy, it doesn't slice up the hands too bad, and it sticks really well, THE FIRST TIME. I use a roller and a pannel popper to smooth it out and force it in to the pores of the metal, but when applying this, I never made me feel like It was going to fall off.

The second skin damplifier pro is awesome. It completely blocked road noise, vibration and unwanted noise. I suspect it'll do well during the summer. I will be buying more of this product. It's better then dynamat.

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.
