KILMAT 80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

I got it for the doors because I put in a new radio. It helped!

I was doing 4 doors and the liftgate, so I only bought 1 box. I didn’t do 100% coverage on the liftgate, but fairly complete single layer coverage on the inside of the door panels (backside of the exterior panel) as well as some of the interior part of the door panel for the 4 doors and had 1/2 a box left over. Used a utility knife and cutting board to cut the material easily. It was a warm FL day so it was easy to roll the material onto the panel with good adhesion. To help cut pieces for odd shapes areas, I put a piece of backing paper in the space and folded or marked it for the right shape like a template. Sound deadening was immediately noticeable, reducing road noise, making the speakers sound much better, and the doors sound more solid when closing them. For even better sound reduction i would suggest pulling the headliner and do the roof too which is thin sheet metal. Maybe I’ll do it in the future. Overall, happy!

It’s cut into lots of sheets. It’s easy to install if you lay it in the sun. I don’t have any oil/asphalt smell in the truck. ProjectTwin has great videos on how to install this stuff. I’d recommend watching them and getting MLV sound deadening material to accompany this. It is my next step.

Had no issues. Has been as advertised, applied but yet to road test for sound.

Used it for my 1971 vw beetle. The engine noises reduced by so much using this! I can’t believe I drove without sound deadening. This stuff sticks on everything. It’s like tar. So even rust it’ll hold to. Even some greasy surfaces it held! I’m very happy to say this is great stuff.

We ended up buying 6 boxes total of this and used on the inside of a Tahoe that is being restored

Very easy to work with and great adhesion. You will need the Norsmic roller to make this job a success. No smell at all. Installed in the rear trunk of a 2015 Kia Forte which sits low to the ground and absorbs a lot of road noise. This quieted things down I would say 90%. Makes for a quiet ride and helped with sound quality as having a subwoofer in the trunk it kept any rattling from happening. Perfect purchase, I am very happy

It does work good but doesn’t cancel as much noise as I expected. In my Polaris Northstar it helped a good bit on noise canceling but still a bit louder than I wanted. Where the Kilmat knocks a home run is vibration from the subwoofer and sound system.

Excellent product. Easy to install and mold to space. Noticeable reduction in noise. Very pleased with result.

Installed in 2015 Corolla. Applied to doors all the floor rear deck spare tire well, and almost every piece of metal and it’s greatly reduced the rattle from bass now I just have to isolate the small parts around the car. This product is overall 5 stars. Easy to apply take the time to use a heat gun or leave the panels in the rear window during the day and they will peel and stick with ease. The warming up of the panel really helps when you need to rool them down. Do not forget to roll them out there are raised squares that need to be fooled out I forgot that and after it was way better once I rolled them out! My first kilmat sound dampening project and I will be buying some more for a future car or the hood well done Killmat
