Bought 1lb Size Pro-Tec paint at ASA Show in New Orleans.........long time ago.
I have original Pro-tec 1lb powder paint in several colors and Clear too. Bought it with several round fluid beds, extra cups, etc. the last time the ASA Show was in New Orleans. How many years ago 25? To answer shelf life question, the red takes a much hotter head to flow out right. All the colors take a little different technique to get good coverage without plugging hook eye. Some have to be swirled a bit, some fast in and out of the bed. All still melt on heated heads. I do mix with clear to get better flow out on some colors. My original, vibrating, fluid beds still work too. All are stored in the AC, in enclosed cabinets, never exposed to light until in use or exposed to humidity (used outside).
