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

I used this for sound deadening in a 1965 Mustang restoration. The sheets are somewhat compliant and very easy to install. I immediately notice the deadening effect as the metal drum effect at sheet metal panels was well damped. I have not run the car yet, so do not know about lasting adhesion, but it seems pretty tight.

Works great if installed properly. USE A ROLLER

My girlfriend installed this in the doors of her 2019 corolla hatchback. You can hear a difference before and after by knocking on the outside of the doors. She also said the car is quieter while driving since the install. Less road noise, etc.

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.

I have used several products like this. being on a budget for the latest project this was the way to go. It works well and was easy to install.

I drive a Ford Excursion and the first project was the four doors, second was the barn doors, third was above the headliner, and finally the rear quarter panels and under the cargo area carpet. Each step yielded an improvement and now that its all done I have to say the interior is so much quieter and the truck feels more solid. Of course it is! Another advantage is the truck doesnt get as hot since the Kilmat is a good insulator even though its inside and the sun still beats on the painted steel body. The a/c cools the inside much faster and more effectively. The next thing is to coat the roof with Line-X and there is sure to be a huge temperature improvement. Great product at the right price. If you want to spend the extra for the D brand, think twice before you buy. Calculate the material weight per sq ft and compare!

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.

Easy to use

I got it for the doors because I put in a new radio. It helped!

Got this to reduce trunk vibrations from bass. Wasnt expecting it to cancel it completely. I was surprised with how well it actually did though. After reading reviews of other more expensive products like Dmat and 2ndSkin. But this product also had good reciews as well so bit the bullet to save some cash and glad I did. I got enough to do my whole trunk and rear deck lid were my 6x9s are by the rear window and had 3 sheets left over. Thinking of getting another box so I can do all 4 of my door but would have a lot left ober after that. So thats still uo in the air but I am going to use whats left from the 1st box on certain rattle poins on the doors for sure. If Youre up in the air about getting this or the more expensive brands just go for it. I know people that have each if the 2 high end brand I for mentioned and Killmat does just as good of a job for about half the price.
