This sound deadener was easy to apply and install. It cut easily with a razor blade knife. It was easy to apply and manipulate. The 36 square feet that was included covered quite a bit actually. I did buy trunk, trunk lid, under the back seat and both front doors. It seems to be a really good quality. My buddy use the expensive Dino mat and I couldn't see one bit of difference. He was actually bummed out that he paid almost double the price. I applied this sound deadener in a 60 degree garage.

Good product, worth the money. Easy to work with, especially if you warm it with a heat gun first. Sheets are small and manageable, I would have preferred bigger sheets for my application. Was enough to do floor and full doors on a 67-72 Chevy pickup.

Bought 2 boxes for a total of 72 sq.ft. Used professional installation service to install the material on all four doors, trunk lid, hood. I installed the remaining material in the trunk myself. Very little change observed on my 2013 Toyota Corolla LE. The installation shop mentioned that the material is too thin, and that they would not recommend it to anyone. For floors and firewall, I decided to use Dynamat Extreme/Hushmat/Soundskins Pro. You get what you pay for. If you really want proper sound deadening, use thicker, highly quality materials.


Edit : I installed Soundskins Pro on my floor (including wheel wells) + firewall, and that deadened some of the road noise. It's much more expensive than Kilmat, but it also has acoustic foam in addition to butyl rubber. If you are cost conscious, you could do Kilmat + some closed cell foam insulation like Noico Liner or Siless 157 mil foam (I ordered Siless foam and will be adding it to my doors + trunk + trunk lid to supplement the Kilmat)


Edit : Changing from 2 to 4 stars. I recently learnt that just adding butyl layer alone will not get rid of road noise, but will help in dealing with rattles. Most new cars don't rattle noticeably when compared with older trucks/pickups/cars. So, if you install just the butyl layer on the new cars, you probably will be very disappointed even with dynamat/hushmat etc. Adding closed cell foam layer will largely reduce road noise and harshness. I added 15 sq. ft of Siless sound deadening foam to 2 front doors and under hood(also look at Noico liner. If your budget is higher you can get the Second Skins Luxury liner Pro). That alone has dramatically changed how the car feels. I plan to add the foam to the other 2 doors, trunk lid and the trunk sides. I am quite confident that the addition should kill off a lot of road noise for me. A more expensive option, but easier to install option is to go for combination sheets like the SoundSkins Pro that includes both the foam and butyl layer on the same sheet (I got those professionally installed on my floor + firewall)

For $35 for 24sq ft this is a steal! Equal to the brands that have been around on amazon for awhile and does the exact same thing. 24sqft was enough to cover all 4 doors on my 2018 Tacoma TRD Off road with double cab. Took maybe an hour a door taking my sweet time cutting pieces and placing them and then using a roller to make sure it's all pressed on. Make sure you rub down the doors with rubbing alcohol first too! Even though my truck is 8 months old there was a good bit of a grime on the metal inside the doors!


The mat is in10x16 (if I remember right) sheets. This made it easy to work with and lay out. A good set of scissors is needed to cut since it is dense. The adhesion was superb and had no question if it was going to stay in place on the roof walls,or floor. I did not measure the decibel levels before or after, but can tell the road and engine noise is less. I had no problems reinstalling the headliner, flooring, or middle console and ducts. It went in a '12 Tundra and I was meticulous and covered absolutely everything that was metal in the cab. I even ran it up the front floorboard/firewall behind the dash as far as I could. I'll be buying more to do our next vehicle
