Works Beyond Expectations

I have a 2005 Chevy Astro passenger van that I completely gutted to turn into a camper van. The van's interior was always noisy, but became that much noisier once all of the interior panels were removed. I have only finished installing the B-Quiet Sound Deadener on the ceiling of the van, and the difference is actually unbelievable. I expect that it will be virtually quiet inside my van once I have the rest of it sound-deadened. B-Quiet Sound Deadener is one of the few products I've ever purchased that truly does what it promises to do!
