A little background:
I was the original Quality Manager at Record Technolgy, Inc., still one of the finest pressing plants out there. I started in 1973, and was their 2nd employee. For the 15 years I worked in that industry, NO-ONE ever knew anything about the "mold-release agent" I now see blogged about every few years. Even our PVC suppliers knew nothing about it. We never applied anything other than a vinyl biscuit & labels to the stampers.
@gasbag, you should have been better at your job and scraped runs that have too much of the stuff in the mix. I'm sick of cleaning it off my purchases
