Review on 🚗 Siless Black 80 mil (2mm) 36 sqft Automotive Sound Deadening mat - Butyl Noise Insulation and Vibration Dampener - Effective Car Sound Deadener (36 sqft) by Jamal Webb

2017 Subaru WRX STI. This stuff is incredibly amazing and it's hard to describe how important it is not only to music but to the normal daily commute. I finished every inch in the door, sealed the door and used moldings to close the back panel. A box gave me a HEAVY cover for 3 doors but ordered another with NO QUESTIONS because that stuff will definitely go on the back panel, trunk and possibly the entire floor pan. Tips: BUY A ROLLER SET. Also throw a clean sheet of plastic (garbage bag) over the door, circle it with a marker, then circle it on cardboard and cut out. Make a front and back and BOOM, you've just created your template for the other side and saved yourself hours. Don't try to create a panel without a stencil, it's a lot easier to have one, lay it on and finish gluing. It's not a quick project, but if you think about it, you know what you're getting into and it's well worth the effort. They did stereo sound (HK Premium) well enough to consider leaving. The Siless side was just insanely quiet and the music was clean and tight like never before. It was louder than the other and you could "feel" the music coming from that side of the car. In general, the product is VERY impressive. Very mild smell when working with it, but not something down in the car now and what in the heat of the SA.
