Review on 🚗 NVX Stealth Black SDBBP40: Premium 90mil Thick Car Sound Damping Mat - 40 sqft. Bulk Pack for Whole Car, Audio Noise Vibration Insulation & Dampening - Ten 18" x 32" Sheets, Butyl Automotive Sound Deadener by Darnell Golden

As I said this is a fantastic product and you can't beat the price! It's very dense in thickness, very easy to shape (recommended to use a heat gun when rolling out for easier installation), very sticky and best of all, it works! Installed in my 92 K1500 which was a complete ratchet to say the least. The stereo would make everything in the truck flex and rumble so much I didn't even want to hear it anymore. I applied it to the main problem areas (roof, door panels, cab back wall) and what a difference! Sounds so solid and very little outside/road noise (and I have a 3" exhaust and Super 10 muffler). There will be a reinstall of the stereo hardware coming soon, so I'll update my review to report any improvements.
