Awesome. Stuck well with alcohol prep and time to let liquid flash-off. Very consistent, piece to piece. Backing peeled easily when desired. Compared to Amazon Basics, the butyl seemed a little thicker (infinitesimally) and stickier, foil was less thick than Amazon Basics. Very good value. Started with my nice car, but after completing project, sound dampened all cars in the immediate family it made such a noticeable difference in sound level and quality of music from soeakers. Recommended!

Great sound deadening material with easy installation.

Size: 36 sqft, Size: 36 sqft

This sound-deadening mat was easy to install on the roof of my Toyota FJ Cruiser. It significantly stiffened the roof and dramatically reduced the wind noise inside the vehicle caused by my roof rack and lights. I can actually carry on a conversation again without shouting while driving on the freeway. The 36-square-foot package was enough for my application, with about three sheets left over. The tiles adhered well to the metal without any special surface preparation. I only wish I had done this sooner.

Works great for sound deadening install!

Size: 3 Pack

I recently put Kilmat in my van I am converting. I thought I wouldn't need to get rollers to install the sound deadening mat in my van but I ordered these anyway. Why not, 3 rollers under $20.00 and I could return them if I didn't like them. Well I ordered this roller set. I was able to put the mat on and smooth it with my hands but these rollers really helped flatten out the sound mat to get better adhesion, especially where I overlapped the seems. The rollers were more necessary than I thought. They are very sturdy and work well. They do not feel cheap and I actually liked them quite a bit. The rollers have smooth function and leave little lines in the mat where I used them. This was very handy as it let me know where I had already used them. It was nice having 3 sizes. The big roller did not fit in some of the curved areas, so I used the smaller rollers. These will work well with sound mat that is thicker than the Kilmat as well. If you are installing sound deadening mat, you should purchase these. I saw other rollers that were more money and didn't have multiple sizes. This was a good purchase. I will try to add a picture to help with visualization purposes soon.
