Works as described. Will be buying more!

I needed to replace the protective film behind my door cards which led me to the creative idea of using dynamat as the majority of that layer as well as placing it in the door of course. I am VERY surprised at how much quieter my driver experience is now and how much noise comes through my doors. I have not done the rear doors, but now while driving, I really only hear road noise from behind me, where I have not installed dynamat. I will absolutely be doing my entire vehicle in this. Solid product

Completely stopped vibration from my trunk on Lexus ES300 due to my12" JBL subwoofer
