Siless Black 80 mil (2mm) 10 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (10 sqft)

This product is easy to apply on vertical planes. I tested it in the front doors of my Nissan Rogue Sport and the sound-deadening effect was quite noticeable. The only downside is that the product is too sticky and sometimes leave glues on the gloves and scissors - so be careful when cutting.

I was apprehensive going with this product as it wasn’t a brand I’d ever heard of before.I placed it on my doors and trunk and while I didn’t notice a huge difference in road noise from using this product I definitely did hear and improved ent from my sound system once installed.This product does have a somewhat tar like smell when installing but I haven’t noticed it lingering after installation.As far as adhesion I haven’t noticed any shortcomings however I did apply product using a roller.

2010 Jeep JK - 4 Door: I did sound proofing on the entire Jeep floor. Easy to install, good quality. Just keep in mind the sheets are folded twice so they are pretty large. I personally like to work with smaller sheets as it requires less cutting. The large sheets would be really good for a large flat surface, but with all the bends and twist, I find working with smaller sheets are easier. I did two other trucks in the past and was less cutting.Just a note to Jeep guys: I bought two cases and it was not enough for the entire Jeep. I was short like 4 sheets, so had to buy another box.Other than that product is great, cuts, sticks and shapes well.

I purchased the black as it was $4 cheaper at the time than the same silver version siless 80mil. I preferer the silver as it is easier to see in dark spaces but seems to perform the same. I only used half of the box on 4 doors so you get plenty for your money and is a good value.

2017 Subaru WRX STI.This stuff is flat out amazing and hard to describe the difference it makes for not just music but also plain daily commute. I did about every inch inside door, sealed the door and used the trim to cover the panel-back. One box got me HEAVY coverage on 3 doors but NO QUESTION ordered another because this stuff is definitely going on rear dash, trunk, and may do whole floor pan. Tips: BUY A ROLLER SET. Also throw a clear sheet of (garbage bag) plastic on your door, sharpie around it then trace on cardboard and cut out. Do one front and one back and BOOM, you just made your pattern for the other side too and saved yourself hours. Don’t try and do a panel without a pattern, much easier to have it, and throw it on there and stick it down done. This stuff is not a quick project, but if you are considering, you know what you are getting into and WELL worth the effort.I did one side of the car and left the stereo stock and tested it against the other with none and will tell you it made the stereo(HK Premium) sound just about good enough to consider leaving. The side with the Siless was just crazy quiet and music was clean and tight like never before. It was louder than the other and you could “feel” the music coming from that side of the car.In all EXTREMELY impressed with the product. Very mild smell when working with it, but none in the car now that down and that is in CA heat.

Great product, great price. Easy to work with and very sticky.

I'm restoring an old car and I fabricated new floors for it, and throught I'll go the extra mike and add soundproofing under the carpet since the original floors had it from the factory. This product is fairly messy to cut as the butyl rubber is like goo and ends up on your blade or shears. Definitely wear gloves and have paint thinner and rags for clean up handly. I also bought a roller to help with the install.The results are what I was looking for - consistent thickness, no question about it sticking to the floor and firewall. One more thing done.

Buen precio y buena calidad , sin olor, fácil de cortar y de instalar , muy conforme con la compra !!

I used this to line the trunk of my miata, it was super easy to work with and seems to have good adhesion (time will tell) so far. I love that it is black so it doesn't appear like you have lined your vehicle in tin foil. Will definitely use again.

This product , to me, is the best application for my needs. Ease of use, quality feel and look.

Good quality got rid of all my vibration noise. Tape sticks very well.

Product is easy to cut to fit and even squish into tight corners inside my UTV.

I've used a bunch of deadeners over the years of competing in car audio events. For regular use it's as good as anything else on the market. I noticed some of the black colour was wearing off but other than that it's great. Probably my favourite brand now.
