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

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

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.

Great Product. I was replacing the headliner in my Monte Carlo SS and replaced the original thin felt with the Kilmer 80 mil Mats.
