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

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!

but i have not yet done a road test.. i WILL report how well it works once i road test it.. adhesion..? YES.. i would say excellent from my short experience.. i applied it to the back side of auto grade cut pile carpet that matches the interior carpet after cutting it to fit the trunk as seen in the pix.. also applying the sound deadening material to the inside of various places in the car as seen in the pix.. apparently GM did not feel they should use adequate sound deadening material inside this 1970 cadillac eldorado which was one of the top cadillac models of the time.. the car is a california car from my home area in san francisco and the SF peninsula where i grew up and spent much of my first 50 years.. the car was represented to be a superior example but some time in its 50 years it was left with water in the trunk.. the selling dealer did not think that an important fact so while there is no rust under the car there sure is a lot of surface rust inside, thus i am now cleaning that up and applying this lead foam material to give this car what it deserves as a 50 year old, 98k mile all original cadillac.. lots of rustoleum paint and other stuff from amazon is giving me something to do while the china covid19 virus is keeping people at home..

Ive been aware of products like this, but never personally used any of them... Until now. This in combination with the Noico 315 Red did great things for a 1999 Dodge Ram 1500 4wd SLT. I covered the inside of all four of my doors with a layer of Kilmat 80 plus a layer of the Noico 315 insulation covering that. The interior side of all doors were completely covered with Kilmat 80, then finally the door panel got a layer of Kilmat 50 over about 60% of its surface. The roof and back wall got a layer of Kilmat 80 plus a layer of Noico 315. I live in the desert and highs in the 110s are a given during the summer. I know these products have improved the cabin environment substantially. Nothing but the sun blasting bare metal then various trim panels on that metal was stock fare in my truck. Im guessing a 10 to 15 degree decrease over stock. Right after I finished the doors I was waiting at a stop light. A trash truck was backing up about 100 away from me. Everyone knows the piercing backup warning beeper. That tone was muffled quite a bit. I havent done the firewall or floor yet. That can wait until the weather cools. My Focal Flax 6.5 components have always been enjoyable, but they sound much more lively than before. The sound system performance has been improved on every level. Highs, lows, mids...everything is better. Doors have a solid feel when closing now. These products are a system multiplier when used correctly. I believe its important as upgrading the various components in any system. A couple other things, I had zero issues with adhesion. This stuff sticks on a 100 degree day just fine! As far as odor. Yes there is a mild tar smell during installation. It dissipates after a couple days. A small, temporary price to pay, for the overall benefits.

My truck is just about as noisey as they come, while I wasnt jumping for joy to do the actual job of installing these, ill tell ya - pretty big difference. After the install i remember my first drive thinking whats wrong with my truck? it sounds... weird - what was weird was that it was quiet! Installing these is a labor of love. Find a nice fair weather day, some shade and put on some tunes and just get it done, if your car is noisy this is your solution. It goes on easy and has so far (1 year+) held up great, I have had to remove my door panels to install new mirrors and took a peek inside and its all held up the same as the day I put it on. I ended up doing nearly my whole SUV, interior, firewall, all 4 doors, the back bed/trunk. Made a huge difference, would do it all over again if I had to. 5/5

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

Worked great! No smell! Excellent adhesion! Wear gloves! Bu where is it now? I do not see it available anymore. I want to order more but can’t.

Good Product.

My girlfriend installed this in the doors of her 2019 corolla hatchback. You can hear a difference before and after by knocking on the outside of the doors. She also said the car is quieter while driving since the install. Less road noise, etc.

I drive a Ford Excursion and the first project was the four doors, second was the barn doors, third was above the headliner, and finally the rear quarter panels and under the cargo area carpet. Each step yielded an improvement and now that its all done I have to say the interior is so much quieter and the truck feels more solid. Of course it is! Another advantage is the truck doesnt get as hot since the Kilmat is a good insulator even though its inside and the sun still beats on the painted steel body. The a/c cools the inside much faster and more effectively. The next thing is to coat the roof with Line-X and there is sure to be a huge temperature improvement. Great product at the right price. If you want to spend the extra for the D brand, think twice before you buy. Calculate the material weight per sq ft and compare!

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
