Review on 🔥 High-quality 315mil/8mm 16.36sqft Auto Heat Insulation Pad Underlay Foam with Self-adhesive | Effective Sound Deadening and Automotive Dampening Mat | 60"x 40 by Dave Hunt

The adhesive is impressively sticky. If it doesn't stick, you haven't cleaned the panel surface well in advance. And you DID use a brier, right? This is good stuff; don't scold him if you've been careless. Despite all the nonsense in the description above (what cotton?), it's just neoprene foam that you can stick onto large panels to muffle the noise a bit. It's not a miracle product and it can tear, but it sticks like crazy and you can't reposition it after a few seconds. Glue it anywhere. Don't try to be 100% covered. Use it in your car doors to make your speakers sound better. Don't use it to deaden record resonance (it's for heavy, thin butyl tar record), use it to quiet the room. i buy more
