Good stuff !
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
This is an excellent product. Easily moldable, cuttable with good scissors or razor knife, very sticky, works great.
This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over.
It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement.
It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way.
Get it. Use it.

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!
