I worked in the Weatherford plant back in the early-mid 1980's. It was a 3M plant then. There were two plants on that site. The one I worked in cut and packed Color-Key. Color-Key is / was used in color printing - as in newspapers and magazines. It had nothing to do with film. They may or may not have coated the product there...I simply do not remember. Nor do I remember what they did in the other plant - may have been film - IDK. I also worked in the Camarillo, CA plant. There was definitely a coater in Camarillo...but they coated magnetic media - tape and data cart's.
