the darkside is loud
Don unless you become a DIYMA vendor which I highly recommend you do, you can't be doing the promotional ads thing such as free samples; and even then not in someone else's thread.I don't know what happened to Thinsulate Acoustic. We used it and sold it for years. It was a great product but 3M gave me no support at all - no technical data and no response when I tried to get answers to QC issues. I believe their primary interest was using it in engineered OEM parts.
The first problem for me was when they dropped the white scrim on the fiber side. Didn't impact performance but made it harder to work with. Then I started getting rolls with big drop outs in the fiber layer. While I was trying to resolve those issues 3M more than doubled the price. Made it untenable for me to continue with the product. I suspect other sellers had the same issues.
