I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Comparable quality and performance to name brand competitor. It sticks on strong, easy to apply, and does make a difference in sound reduction. Turn your hollow shell sounding vehicle panels into solid sounding walls.

Must for subwoofers. True 2mm spec. High quality.

Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)

Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.
