I just checked the PPG color library and the formulas for DBU and DCC are not listed.PPG seems to be deleting all the old colors. I have checked my paint mixing station computer also. My paint rep said all the old color formulas should be listed in the color library on line but they aren't there. We have gotten color formulas by using a spray out panel with any available line(OMni,lacquer.acr enamel,ect)and had a Prophet color scan done to get paint in any system we need. I'll check again with the paint rep and see why the formulas are gone.
