You need to call the PPG library and see if they have formulas on file that jobbers do not. I do it often. Ermine was available in Concept. Or just use another paint company. When painting bikes I sometimes have to use R-M or Glasurit becasue PPG does not have a formula, and time does not allow for a lab match. Once someone has a lab match done, it is entered in their system. Not sure why you want to use BC/CC when shooting a solid color. If additional UV protection is preferred, you can cocktail the last coat/coats of Concept with clear. Black is a different story. SS black shot and then cleared has more depth than BC/CC.
