As described, very sticky backing..
Very sticky backing. Once it down ,its down. Good sound barrier, and help the vibration of the gas tank I carry on the truck.

Easy to use and did the job!
This worked perfectly to patch under hood insulation that was shredded by a squirrel. I just needed a small amount and this was a reasonable solution.

Easy to work with and apply this great deadening material!
The material was well packaged and arrived in good condition. The material is easy to work with, and the adhesive is very sticky. The material is very easy to cut and apply. I applied it to a metal cabinet that had a tinny ring to it before the application. After applying the material, tapping the cabinet produced only a dead "thump". I believe the material will work very nicely as a deadener.

Great noise dampening but awful deformation and residue when removing.
Not bad in terms of noise dampening but once cut and removed from the back the foam starts to shrink and deform. Also if you want to remove it without any traces afterwards good look this stuff is impossible to remove without residue.

Good price
Great value for the amount you get. The quality is really nice and the glue is super strong. Once it sticks it’s on there for good.
