From post #33 above: Here's a link showing William's R-M book reference. http://documents.clubexpress.com/documents.ashx?key=Mn9lNR5oNp9Osk1Oybo9zXiUl8H2ZPEfYNR%2fojqMOY6daTf3pOKmoYhGMkL2rkQ%2f
Looking at the Camaro charts for 1968 and 1969 the back window lower garnish is listed as black A-946 (semi) for the 68 and black 168C41 (suede) for the 69. Am I not a professional painter so I freely admit I can be missing something. It also appears for the 68 that note 1 would allow the painter to adjust the amount of "flat" (849 suede concentrate) that can be added and needed to achieve the desired look. Again I can be way off on this too.

The A-946 tintometer formula is for standard gloss, flatting agents are used to achieve desired gloss. Suede additive is also added to achieve desired texture. A-946 is just black off the mixing bank, and then you add to it. You'll see that A-946 is also for Tuxedo Black, the exterior color. Unpolished lacquer produces a semi-gloss finish. The Fisher (GM) Code is what you would give to a jobber. It helps to have the correct manufacturer code.
Now, if you look at a PPG book, the codes are for what the formula actually is. 9300 is black off the bank. But the interior codes are listed as 9317 and 9248 for '67, and 9317 and 9266 for '68 and '69. You are correct in your observation of the R-M book that the tints must be added to achieve the desired effect. Anyone can call BASF or PPG and talk to the tech line or library, and they will provide you with a formula if you give them a code. Explain to them what you are trying to do, they are more that willing to help. A jobber will not always be willing to help you. Some are more helpful and knowledgeable than others.
Most shops just mix their own to hit their target.
