Although an official GM touch-up paint is not available for the base 5-spoke wheels the following alternative available at your local autoparts store is available:
Plasti-kote Scratch Color
GM 3845
Followup from Corvette Action Center Member:
"I could not find the listed paint (Plasti-Kote Scratch Coat GM 3845), so contacted the manufacturer and found tha it has been discontinued. I asked them to specify as much detail as to the make and model and year that this color was used for, so I could find it through another supplier and was given this and hope it helps everyone: "The GM 3845 part number is designated for General Motors vehicles from 1985 thru 1991 with paint code 12/WA8535."
