I'm not painting wheels but trying to match the wheel color for a second color accent stripe on a quick silver C6 with QX1 wheels. Someone did find the wheel color code and for those that didn't see that message it's - "Gunmetal Metallic" code WA924. Turns out to be an fairly old paint color first used as an accent paint on Chevy and GMC trucks.
Thanks to all for the assistance. I'll try to post a picture or two when the project is completed.
