Sound Deadening Material for Cars 157mil (4mm) 6sqft Adhesive Automotive Sound Dampening Foam Mat Soundproof Deadener Closed Cell Foam Noise Reducing and Heat Insulation for Vehicle Van Truck - 1 Roll

Good price for what it does. I cut my patterns on the outside of my car for quarter panels and peeled off adhesive pepper as I put them in place.

Horrible. Foam falls apart when pulling of backing. Very sticky but junk foam

Easy to apply and works great! It muffles the noise of the engine well.

Mat works great. It is not stick on, you have to tape it on. Doesn't mold to the shape of things that way.

On the first door panel I noticed that the black adhesive comes off all over your hands, It's difficult to get off; good scrubbing takes care of it (I didn't need to use Acetone or mineral spirits fortunately) but they should have a sticker or something warning users about that. On the second door panel I wore nitrile gloves and glad I did.It seems to work well, and you don't need one of those rollers to place it properly. In the photo it's behind the plastic, lining both the panel and the accessible part of the inner door. So far so good

Does what it needs to do! Dont wear gloves and dont pull the paper until you’re ready to place it. It is STICKY LOL

worked perfectly. sound detinner and insulator.

The paper backing had dried out and came off in pieces. The foam did stick to the surface but crumbled when I tried to move it slightly. I believe my order had probably been in storage for some time.
