[QUOTE="Rudy, post: 4215169, member: 568035"] There are standardized tests for vibration damping - ASTM method E756 is the best known. I don't see anything wrong with the adhesive used on UE - unlike the v1² which has had several reported failures and is very easy to see why it fails in testing, but the Mylar facing is a terrible mistake. Research "constrained layer viscoelastic vibration damping" if you want to know why. It's not just about adding mass, it's also about CLVED and stiffening and Mylar is sh!te for that. You want foil and the thicker the better. Works much better as a barrier too. These eDeads are flashing tapes. They just turned the machine up to 11 for UE. It's pretty obvious that they wanted to be able to brag about thickness. Fact is, in many places, this stuff is thicker than you need, so you are effectively throwing 1/2 the product away and adding unneeded weight to the vehicle. Butyl will burn. Aluminum foil will do a much better job of snuffing ignition than will Mylar. [/QUOTE]
