Sam,
Gotta love those wheel covers!!! Great color combo too! I am putting them on my 67 RS convertible too. It's a power disc brake car, but I am keeping the rallys on both my 67 IPC and my 67 BB Zone car.
I have a Body Broadcast sheet from a 09C R-1 Norwood SS with these covers and they did the face of the wheels in Bolero Red. This is an early car though. To me it seems that GM went to painting the face of all of the wheels with full covers (N96, P01 and P02) gloss black enamel. Of course, the cars with the base hub cap were still painted body color through out the year. So, this one is a bit of a toss up. I am guessing from the fact that you have an FC wheel that your convertible is an SS or has the P12 option.
If it were my car I'd go with the gloss black enamel face and PPG DP90 black epoxy primer before the paint.
How about posting some pics of the car ( I got a look at it on your clubs website)?!?
Hope this helps,
Mike
