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

I have been in the miserable world of custom cars for over 25 years. i only found a couple honest knowledgeable reviews. I doubt this qualifies as knowledgeable but, I do have some feedback. Does it work? Yes, it does function as sound deadener fairly well. For what you pay this is pretty good. Is it Roadkill or Dynamat ? Nope, that in my opinion is another class of product. I used this on a 77 Toyota land cruiser that has a total budget for upgrades and has a must have list. To cover the same square footage would have been nearly double the money in my preferred brand. I sat down and read the reviews on Amazon and a few other sites. After I hadthe cargo area done I was overall happy with the purchase and continued to finish out the entire vehicle. The first big difference is the adhesion. It is noticeably less than a name brand and requires a bit more surface prep and cleaning to get the maximum sound deadening. That is one of the biggest mistakes you can make with any brand sound deadening product is to not get it stuck to the surface with as few and as small of an air gap as possible. Getting this to stick in all the little cracks without some release takes a bit more work. Is it as dense as a name brand ? Nope again. It is about 80-85% as dense as a name brand . You can hear it after it is applied and feel it when it comes out of the box in weight. The weight is a bonus as it is lighter and i would use it again in a hot rod or go fast project where you were trying to bring down sound while not trying to turn the vehicle into a brick. i did not have a way to compare the heat loss from the application against another brand at the time of this review. I would suspect it to be about the same in that aspect as well in being well sufficient but, not quite as good as a name brand. It does seem like I am hating on the product but, in fact I am not. i would use it again and will for the price. Overall it is a 3.5-4 star product. If value it on price equal to performance it would easily be 5 stars. I gave t the review and rating I did based from use of top tier brands compared to this product. If you are looking for the maximum sound control and heat loss buy a name brand and apply it properly but, have deep pockets. For a budget minded person looking for significant results and still have some money for other parts of your project buy with confidence. I will reiterate This product does take a little more elbow grease to get proper adhesion, buy a good set of rollers and wedges and make sure it is stuck down. No replacement for good prep and proper installation.

Before 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.

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

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.

Made a huge difference. A little bit of music can now go a long way. And i have a lot of music. Installed in my trunk and under my trunk mat where my spare goes. Put some in the door too. The shaking went down to a huge minumum and also my sound stays more in my car than before. When I open my doors its a huge difference now. Makes road noise less as well. When i get the time im going to install in my wheel wells

I installed this throughout my Montero Sport, mostly in the rear cargo area to quiet the many rattles that come from 200k+ miles of driving around Montana/PNW. I pulled off the interior trim panels and placed a layer on the inside of the exterior sheet metal fender panels, then a layer on the inner sheet metal panel that frames out the cargo area and the trim panels clip in to. I got about 70-75% coverage, mostly because I was being a little lazy and a bit rushed, but I also didnt want to interfere with any holes that were used for trim clips. Or run out of the 65sq/ft before ordering more. I feel like the 80mil material is heavy/dense enough that 100% coverage wouldnt really be necessary. I did do both front doors so far, along with most of the rear and there is definitely a difference. A lot of the rattles are completely gone, while the bigger, louder noises that came from offroad driving are considerably quietier. The loud banging from rocks getting thrown into the wheel wells is much less noticeable. The doors close with a much more solid sounding thud with no rattles then before. I have decent Rockford speakers in my doors but nothing loud enough to notice any sound quality differences as far as stereos and such are concerned. This product will probably stick to anything, but I strongly suggest giving the surface a wipe down if its dusty. Its repositional as long as youve only got a few square inches stuck down, any more than that and good luck. Cuts pretty easily with a utility knife on a scrap of OSB or something. Definitely worth the money and time invested to not hear everything rattle on long off-road trips.

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

If you have ever had a rattle trap fbody, you understand that the road noise is horrific, and theres alot of squeaks . In an effort to make the car more enjoyable on a highway drive, I figured Id try it out. I got way more product than I had figured I would get so thats a plus. The key is to hit the main areas of noise, not every single square inch. Thats just added weight with no real benefit. It did help the road noise a good bit and I still have like 6 sheets left to install in my trunk pan. I took the car on a 1600 mile trip shortly after and enjoyed it so much. Buy the $10 rolly tool they recommend, its very worth it, and wear gloves. That foil is sharp! Ill be ordering some more in the future for my door skins and up in the headliner area.

Awesome product. Installs very easy. Really made my cab quieter in my 99 7.3 Powerstroke. Tech tip leave it inside somewhere cool until install because it gets very mushy and messy when warm.

Good Product.
