I'm not sure this will help, but here goes: When my wife did our coupe, we went according to an article by Bill Reeder in the second volume of How To Restore Your Model A. She used DuPont Lucite acrylic lacquer Russett 12, Code: 68CN (a GM color). The mixture (as per the now dried out can) is, in parts:
453 FER yellow (HS)............. 1.0
406 Black (HS)....................14.0
401 White..........................33.5
467 Flat base......................56.5
4528 Flat Compound............109.5
428 Red Oxide....................227.0
465 Binder.........................445.0
Unfortunatley, this was done 22 years ago and I don't know if you can cross reference these numbers with a modern formulation. FWIW, the work came out exceptionally well and still gets comments today. Maybe someone can give you more up to date information; if not, this may be of some use. Good luck.
