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

I used this on my wheel wells and part of my roof. I couldnt be happier with those product. It made a tremendous difference in road noise. There is a rubber or tar smell when you first put in on but it dissipates after a day or so. I left the doors open to let it air

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.

Accurate and fast delivery

OK, first of all Ive been professionally taking cars apart and putting them back together for the last 7 years as an autobody/refinish tech. You see some cars with little to no sound deadner and some higher end cars with lots of it. Eventually you come to see/hear/feel the difference this stuff actually makes for cars that didnt have it at all or have very much of it. Weve always used the 3M sound deadner pads that are shiny, black, and come 10 large (19x19) squares in a box. Did a 2008 Crown Vic with those, they worked well. Those are much thicker than this stuff and weigh a fair amount more. (NO, Im not complaining about weight) I just always thought that if it was heavier it HAD to be better. Well, Im working at a different larger shop now, and it wouldve been harder/more expensive to get the 3M pads, so I gave these a shot. I had to do a 2011 Hyundai Santa Fe for noisy/hollow sounding doors, a couple of which pinged like a drum head when they closed, thanks to the foam/adhesive breaking down on the diagonal support inside the door that the door-skin is bonded to. So, I did a few big strips, (it does not need to be completely covered!!) inside all 4 passenger doors, and rear gate. The stuff cuts good with a sharp box-cutter (watch the foil edges) Also, it sticks very well when pressed or rolled into place. I then added some Noico red foam to help with additional road noise dampening and insulation. I know some people complain about the smell but I never noticed it at all in the Hyundai or my 2018 F-150. This stuff worked great! got rid of all of the pinging/hollow sounding doors and it also gives you a pleasant increase in sound quality/bass response even with stock speakers! The Hyundai doors now sound like closing the doors on a car 3x its price tag with by doing that. They sound nice and solid now when they close. I also did all the doors on my 2018 F-150 with the other half of the box of this and the Noico foam, good results there too!! I will still have a small amount leftover that will go somewhere in the F-150 cab. Good price! Definitely recommend to get rid of hollow/cheap sounding doors or added for those looking for better sound!

This product is easy to use. Extremely sticky, great adhesion. The bumpy pattern realy helps to let you know where youve rolled it out.

This was really great quality insulation - stripped my car to the frame (removed trim and chairs etc) and adhered it to the frame itself. Easy to cut the pieces down to size with a simple box cutter (though will get gunked up over time with the black stuff inside). Put it down, kinda use a flat surface thingy (I used an old name tag from work) and then went over it with my hands (the heat from your hands helps). Now my car is clean, quiet and warm in this cold front were all having. Highly recommend if youre looking to quiet your car from outside or engine noises (Id say a good 20-30% decrease from before I did this). Very happy with how it turned out.

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.

I applied this to the inside of the thin sheet metal on the top and side panels on my Samsung front-load washer and dryer in an effort to quiet them down and eliminate rattling and vibration. It worked amazingly well! Just wish I took pictures while I had it all apart. Also applied it to the bottom and sides of my custom made 14ga stainless steel bathtub of a kitchen sink. It worked fantastic there too. Great stuff!

I just applied this to my 3rd Gen 2018 Toyota Tundra Crewmax, which has a big cab you should know and it sounds better and I can see some noise cancelling coming from this. I used 2 packages total and for my all my door interior panels, back seating and back panels and I need to order another set. There was a smell that lingers for a couple of days but it literally disappears after that! Every review made it seem like it was unbearable but truth is that once you get it applied just apply some air freshening deodorizer and itll go away within a few days. It sounds fuller and quieter. Everything on any new car, except a rolls royce I guess, gets a ton of exterior noise level! The adhesion is good as long as you got a reliable roller too by the way. I have yet to do my firewall, driver side and transmission/center console hump so thats next. If Im doing the headliner, Im going to consider doing a insulator and sound Deadened for that instead of the kilmat. And a note for anyone with open and spacious big cab or interior, please consider ordering more than just what they recommend on their sizing. I followed that suggestion and I really recommend ordering a couple more than expected. For Tundras probably a good 4 packages if you are doing all everything. And if youre on a budget so far this is the best way to do it.

Being the first time I have used this I didnt know what to expect. Was it going to be hard to install? Would I hear a sound improvement? I was watching videos of people installing it and they said to let it heat up in the sun. There is a point when it gets a bit to hot and it flops around and is super sticky. I was putting this in the door panels of a 2019 Honda Civic 2dr. Not a lot of room to work with and it wants to stick to every little thing it touches. Not a bad thing but just takes more care to get it in there. I did the bottom 2/3 of the doors. Now when you tap on the doors its just a thud. Overall sound from the stereo was improved. The low notes are now MUCH cleaner! The bass guitar sounds like a bass guitar and not just some humming low note. Same goes for the bass drum. Much more defined and musical. I cant say anything about noise reduction from outside the car yet because I just havent driven the car enough. So for under $50 its worth it in my opinion.
