Second Skin Damplifier Premium Car Sound Deadening Material (1mm) – Butyl Rubber Auto Sound Deadener Mat (10 Sq Ft, 5 Sheets) – Made in The USA

Used to deaden the horrible sounding vibrations on a plastic rear deck with lots of nooks and cranies. Worked perfectly, adhesive worked perfectly, could cut easily. Once it cooked in the sun for a couple of hours it got even better!! It does have a light odor that is the nature of the chemicals that make up the item. Nothing that won't dissipate, I am sensitive to smells/fragrance and this was a low odor product once I got around to install it. I had aired it out for several days prior to install.I would recommend building a minimum of two layers for problem areas. I was able to cover my rear deck (buick park ave) about 80%+ covered with 2 layers and have one and one half sheet still left of the 10square foot pack. The black coating on the aluminum layer does not come off easily, I was not able to scratch it off during the install and flatting procedure. Very happy with results and the ability to cut with scissors to quickly install since there was leading edges around all 4 sides to be able to peal off the sheets without ruining part of the panel you are holding trying to pick it off.Product was installed 7-22-17 so if something changes, which I doubt from reviews this stuff just won't release like other sound attenuation material adhesives that fall off in the heat, I will update. The fact it worked better after cooking in the sun speaks that it is pry really stuck on now and I don't expect any failures. The seller was very quick and thorough in their responses. Obviously passionate about their work and product.At this point I would totally recommend this product over more expensive competitors.

I acquired samples from a few popular manufacturers of their sound deadening products ranging from Second skins 40 mill Damplifier product to asphalt based 110 mill thick and 80 mill thick butyl. I applied these samples to 2.5" x 6" heavy gauge steel clips I got from a lumber yard and hung them from wire in my garage. After striking each one with a hammer to hear for myself which one was more effective I was blow away by how much more effective this thin butyl CLD product was. I thought the 40 mill thickness was going to be its weakness and I was wrong. It was by far the most effective one at reducing the vibrations and ping after my hammer struck each sample. I was a skeptic but now I'm a believer that Second Skins Damplifier is extremely effective at doing what they claim it does. If you're going to go through the trouble of spending your weekend taking your interior apart than don't skimp on the product and get the best one for your money. I will be installing this in my brand new CX5 for sure. I also want to say the quality of this product is excellent. The aluminum constraining layer was by far the thickest of them all and it actually feels like real aluminum (some were questionable). It's also light, which for me is important. BTW I only covered 40% of the surface area of the clip and I feel this is more than enough to do the job. Any more than 40% coverage is not necessary and won't give you much benefit in return.

Bought this to reduce noise in a Honda Element. Easy to work with, bought the 1mm thickness & it did the job of reducing that tinny sound in the doors & roof. My son used this on his Element & recommended it. It’s a little more expensive but an excellent product.

I used Second Skin Damplifier Premium Car Sound Deadening Material (40mil) – Butyl Rubber Auto Sound Deadener to reduce the noise coming from the rear hatchback area of my 2019 Hyundai Ioniq. When driving at 50+ mph the people in the back seat had some difficulty following the front seat conversation. After doing some research I discovered that it is not uncommon to get a rumbling noise from the trunk area of a car because manufacturers skim on sound deadening. This is the case with the rear hatch area of the Hyundai Ioniq. Apparently, one of the causes of this noise is that the metal begins to resonate at certain speeds and it can get kind of loud.Anyway, my research also led me to buy the 2nd Skin sound dampening material described above. I was very impressed with how easy this 2nd Skin product was to install in the spare tire well under the floor of the hatchback area. The material easy cut with a pair of cheesy scissors I had almost stopped using. I dry fit each piece making cuts where necessary, such as around the fitting where the spare tire is screwed down and any places that might require mechanical access in the future.I purchased one box of the 2nd Skin material and it was enough to do the entire spare tire area, but only the spare tire area. Each piece was rolled flat as directed by various Youtube videos from various installers of 2nd Skin and other sound deadening manufacturers products.It took me right at one hour to get the job done and then another 10 minutes or so to get everything picked up and put the spare tire and gear back in the car.Afterward, we went out for a drive and there was a very noticeable reduction in the noise we were hearing. The passenger was able to hear the conversation going on in the front seats without any problem.At some point in the future, I may sound deaden the inside of the right and left rear quarter panels of the hatchback. I expect that will make things even more quiet in the rear seat.Overall, I was pleasantly surprised by the quality of this product, and how easy it was to use and most important...it solved my noise problem with minimal cost and time.
