Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.

The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil

Easy to install in a vehicle! Helps keep the heat out as well as keeping it quieter inside my car. Self sticking to the inside of the roof without strong smelling adhesives. The quality of these pieces work very well in my vehicle!
