KILMAT 50 mil 50 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Ive built motors, done extensive bodywork and made all kinds of modifications to vehicles. Sound deadening is by far my favorite. The install isnt fun by metric. First, uninstall your entire interior. Clean the inside of every panel with isopropyl alcohol. Grab a rolling pin (they make specific tools for this), cut your acoustic mat and be prepared to spend the next 8 hours in a sweaty and cramped position. Cover every square inch you can- it really does make a difference. Put in the hours here, and enjoy it for the rest of your vehicles ownership. Not only does this make your ride quieter, but it feels more luxurious, too, since the deadening material has the additional effect of quieting down interior trim rattles. My old Ford Ranger is now quieter on the highway than my BMW 5 series (seriously!). The 50mil Kilmat is not the thickest option, but it is an outstanding value when Dynamat will sell you the same basic product (foil-layered tar) for twice the price.

Product was used in a 2018 Chevy Express Extended Passenger Van conversion. After gutting the van we lined the entire walls in back and side doors, wheel wells and ceiling with the product. On our first short trip to a National Park we were amazed at how quiet the interior was on the highway. We could not hear most cars passing by and semi trucks were very muffled. The only doors we did not apply yet was the driver and passenger doors and yet the sound dampening was awesome. The application process was fun and easy. The lines on the foil backing made it easy to measure and cut straight pieces to fit where needed. We did purchase a heavy duty pair of scissors at the DIY store for under $20.00 which made the cutting of product easy. We even used some of the backing paper to create templates of some of the more challenging areas and used outline to trace onto back of product for a perfect cut and fit. We purchased two boxes and have a half a box left. Oh yea, we also purchased the metal rollers recommended for pressing the product securely against the area applied. One more thing, one of the reviews for this product recommended using a metal spoon to press product in hard to reach areas and it worked great.

I liked thet price and how easy it is to use under carpet on 1980 El camino

Works amazing just some places needed too be doubled up

***update*** I updated rating from 1 star to 4. The smell was faint but did seem to go away. Car is in garage and hasnt been exposed to sunlight yet, but hoping there is no smell. So based upon reviews I decided to purchase the 50 mil x 50 sf package. My main concern prior to purchasing was a chemical / asphalt smell, and most people stated there was zero smell. Well, thats not true at all, there is an asphalt smell. I havent even peeled the liner off and I can smell asphalt coming off the sheets. After spending hours scraping off the old sound deadener and prepping the panels, do I really want to stick on this stuff? Also had a bad experience in the past using Fatmat about 10yrs ago, and that smell never entirely went away and was extremely strong after installation and actually gave me headaches for weeks. That purchase was also made based upon price. So now, trying to decide if I should send this back or not. Im leaning towards sending back, I cant deal with that situation again Id rather just spend a little more and get a real true high quality Butyl product instead of asphalt. You get what you pay for....

This was used in a Ford Transit Connect Cargo Van. I have plans to convert my work van into a light use camper when traveling. Used it to reduce the noise from wheel wells and the bare roof. Eventually I will insulate also. Easy to cut and flexible. Use a good roller.

The best

Adheres well if you actually do it correctly. I double layered every large hollow hole and it turned out nice and sound. The door no longer shakes at a idle.

Great product! Like the results

The mats were very easy to cut up and install inside the interior of my car. Road noises sound muffled which is very nice and vibrations from the subwoofers have less rattle which adds thump and tonality to the music. This stuff is really great and idk if it’s just me but I love the smell of the adhesive, it made installing this very pleasant :)
