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

I’ll start by mentioning that I’m a professional car audio installer with multiple awards at an international level. I’m not some kid working on his bucket in his parents garage. I first noticed that this material seemed thinner than the claimed 80 mil. So I put a set of digital calipers on it and the mat is closer to 70 mil. Secondly the adhesive backing was less effective than what other products I had worked with the past. But what prompted my return was the fact that unless I applied 3-4 layers the product was ineffective. Check the weight of this product compared to 36 sq ft of a comparable product. You’ll see that Kilmat weighs almost half of what any quality mat weighs. Very misleading. There are plenty of other quality alternatives to Dynamat on the market. Unfortunately this is not one of them…

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

Worked 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.

This product is very easy to used and performs as advertised

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.

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..

The sheets make easy work of applying the material in tight spaces and even cutting pieces to fit odd shapes. I used about 4-5 sheets per door for my Ram 3500 Mega cab. Upon opening the door cavity, there was two tiny sheets of OEM soundproofing on the rear doors and NONE on the front doors. I applied the sheets in as large a piece as possible. I used a heat gun to warm the door and the material. Adhesion is excellent and I used a mini roller to push the material flat onto the door panel. I also used a torpedo level that had a rounded plastic tip to push the material flat in hard to get to places. Id say I covered 99 percent of the door with 4-5 sheets. I also put some of it on each interior door panel around the speaker grill and near the molded armrests. the door panels went from a gong like sounds to a confident dead knock. the door also closes with a definitive thud sound. over all the product is excellent and affordable. I wouldnt hesitate to get another package to place more around the car as I build the system.

Great product easy to work with and install! Follow the directions and use the correct tools its a No Brainer

I mean you get what your paying for. My car already has almost 36 cubic feet of Ballistic deadener. That’s my last piece , and I want to say that one weighs about the same as 5 sheets of the Kilmat. As you can see the kilmat will take up more space. That might good for some, but I’m pushing my Jetta hard for SPL and I been getting some very annoying rattles still. So there’s a few spots I missed with the Ballistic, but I wasn’t trying to spend $200 on more of that so I got this kilmat. I’m sure it’ll get me there right. However I’m 99 percent sure if I originally got kilmat I’d be very unsatisfied . I didn’t want to wait on shipping or pay too much. There’s only the roof and a few odds and ends left to do so I’ll just double it. If your just trying to remove trunk rattle for a 500 to 1200 watts setup this might be ok for some. Maybe the doors . But if your like me, there’s going to be much more you’ll need to do, this aint gonna work

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