We now have the new version of 60 mil in stock and it is now shipping. The main difference between the new version and the old version is the wax paper. The old version on some rolls would have issues with the wax paper coming off when the deadener was hotter than 90 degrees. The new version's wax paper comes off a lot easier. It still comes off like a champ when the deadener is 135+ degrees. By switching from the brown wax paper to a white film it got rid of most of the wrinkles in the aluminum. It also made the adhesive more consistent in size.
Here are some pictures of the new version compared to the old version, the new version is on white film and the old version is on brown wax paper.
The new 60 mil is $58.99 + shipping for 25 sq ft ($2.35 a sq ft + shipping) and can be purchased at AudioTechnix.Com
