Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
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!

Makes For Quiet Rides
Model: 10 SqFt(0.95 SqM)
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.

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.
