Review on 🚗 Ninety-Mil Thick NVX SDBP40 Car Sound Damping Mat - 40 sqft. Butyl Automotive Sound Deadener for Audio Noise Vibration Insulation and Dampening (Ten 18” x 32” Sheets) by Hector Watkins

ONLY used! NVX 90mil for over 8 years. NEVER withdrawn. Love you, EXO and Ed, but if you prep the surface "spray with water and dish soap" before application. Good luck with the takeoff. It has doubled in some places. The best soundproofing for the price! and depending on the project, 40m² fit in a small car or truck. Tip: You don't need 100% coverage, 70 to 80 is good enough! for most jobs.
