    Best deadner I’ve ever used

    Posted by Marc Campanero on Apr 05, 2023

    Easier to apply than the other brands I’ve used. Stick’s very well. So far I’ve applied to my trunk and roof. I hear a lot less noise already.

    definitely worth it

    I installed this set on the c pillar back, including hatch door, and the two front doors in a subaru wagon. I also went to home depot and bought a roll of carpet padding with the moisture barrier to cover the deadener where all the metal and plastic touched, and to fill in the spots between panels where there are dead air pockets. It made the doors heavy and solid with no metallic sound when you tap the panels from outside, and it killed 99% of the rattle. Bass feels louder, and it sounds clear and crisp. Absolutely worth it!
