Maybe we got a bad batch, but we scrubbed the inside of his car with alcohol before we put the mat on. After most of it fell off he replaced it with less layers of fatmat and there have been no problems since and better vibration damping. Also, I could easily rip the eDead apart because its was thin and didn't have a foil backing. I bet it has improved, but from my personal experience with the stuff I wasn't impressed.
