So, I dont know about you guys, but.... I can look for something for a month and not find it, but as soon as I publically ask for help, I find it. No wonder we don't want to ask for directions. Happened here.
I called the PPG Color Library and had an aswer in 15 min. These guys were great. They also did a conversion from laquer to acrylic and sent me the code.
BTW - the PPG Prophet Code for 66 Dark Red interior is 71541 in case anyone else wants to know.
