> 3 dayFirst time using this and was very pleased. I made sure to degrease the floor and make sure floor was dry. I liked how the sheets were in manageable sizes and this was so easy to cut when I needed to trim off pieces. I didn’t cover every inch of the floor and figured even if there are small gaps it would be better than before. Very easy to use. One box completely covered the floor of my crew cab.

> 3 dayBefore purchasing, I researched several manufacturers of Sound Deadening material. I drive a truck with off-road tires and enjoy quality sound from my radio without road noise interference. All of the leading manufacturers of sound deadening material use butyl rubber in various thicknesses. I bought the .80 ml thickness from Kilmat because of the positive reviews and the price. I installed the Kilmat material in all four doors and on the back firewall. While I don’t have a decibel meter to provide firm data, the decrease in road and tire noise after installation was noticeable and, in fact, I would say surprising and significant. I definitely enjoy driving on the highway more in a quiet vehicle. My guess is that it decreased road noise level by 30% or perhaps more. The key is to buy enough material to line the “inside” metal skin of your “outer” door as shown in the photos. In summary, the purchase was well worth the effort and cost.

> 3 dayI used this on the rear deck of a 2019 acura tlx with a kicker 8 inch sub driven by 200 watts rms. The metal was flexing very badly and the noise from vibration was horrendous. One layer of killmat completely silenced it.

> 3 dayI have a 2013 Mercedes C300 4MATIC. The only place on the vehicle where they do not add sound deadening insulation is in the trunk, where the spare tire lies. I decided to give this a shot because it had a 5 star review. Well, it did not let down! There is a noticeable difference in the road noise. I am very OCD about things, and this took care of all my worries. I utilized the 18sqft package, and had one mat left over. I did a full layer covering the entire spare tire well. It took about 2 hours, with the assistance of my wife. I would highly recommend getting the roller to get air bubbles out and to ensure proper adherence. Prior to installation I cleaned all surfaces with rubbing alcohol and ensured that all particles were swept out. I DID NOT utilize gloves, nor would I suggest it because they just get in the way. I took her for a drive down the interstate immediately following install, and all I can say is. WOW! Definitely worth the $50 bucks. Truthfully, it does not look all that bad, either. All of it is hidden under the spare tire carpet covering, so you have to lift that up before you even know that it is there.Thank you KILMAT!!!!

> 3 dayIve done all sorts of upgrades/enhancements to my cars over the years, and installing sound deadener has been the most transformative. Sure, upgrading the stereo/amp/speakers all at once is hugely transformative, but its also expected to make a huge difference. The reason I say sound deadener is more transformative is that it improved things in many unexpected ways, on top of the expected reduction in road & mechanical noise. Background on my vehicle: - Medium sized pickup truck with extended cab - 2006 but only 40,000 miles, so enough miles to develop some rattles - 4 doors (2 normal, 2 smaller) - Smaller doors provide access to extended area for storage or jump seats I took the driver/passenger and jump seats out but only moved the carpeting out of the way vs fully removing. This, and because I didnt remove the center console, meant that I was able to cover the sides of the drivetrain well but not the top . In my truck, most of the mechanical noise comes from the engine, not the drivetrain. What I covered with 72 sq ft of 80 mil mats (i.e. purchased 2 boxes of 36 sq ft): - 4 doors - Rear of extended cab (area facing bed) down to the floor - Ceiling - Driver/passenger footwell up thru firewall - 3-4 wide area running between seats and doors from front to back - 2/3 of area below drivers seat (was too lazy to remove passenger seat again just to apply a single sheet) - 1 sheet of mat leftover I was very thorough. I removed the speakers in the doors and covered the area behind them (I also installed speaker baffles, which improve the sound quality and provide some sound deadening qualities). The rear doors have built-in pocket storage areas so I ended up covering the exterior metal panels of the doors and the some of the interior metal panels. Maybe overkill, but those doors were also the source for a lot of road noise. Expected improvement: significant reduction of road and engine noise. This stuff delivered the goods. My 9 y/o immediately noticed the difference and said something before I could tell her I was done. And this was on city streets, so not even highway. Its that noticeable. Hands-free phone calls, music, talk radio, you name it, all sound much cleaner, crisper and without having to crank it up as much. Unexpected improvements: - Doors close with a more solid feel - Near silence when going over potholes and changes in pavement - Sensation of that I installed a new, more sophisticated suspension because everything feels tighter and smoother All in all, money well and one weekend well spent. Installation tips: - Run a small heater if installing in temps below 60 degrees. The mats will adhere better. - Buy the metal rollers to make sure the mats are completely flat and fully adhered. - Before removing the paper backing, put the mat into the desired location and press hard on the areas that need to be accessible (screw holes, wiring, etc) to create an impression. Then use exacto knife or razor blade to make the opening marked by the impression. Be sure to double check all access points twice so you dont find yourself all ready to put everything back together and you have to find the one you covered. For rubber gasket access points, I cut a path around the edges so you can remove the gasket, but theres still mat on the bulk (center) of the gasket.

14-04-2025Worked pretty well for quieting my car down. It’s easy to cut to size and to apply, and I didn’t notice any smell. Id say I went for about 60% coverage and ended up using about 1.5 of the 3 boxes I ordered.
