I have some curb rash on my 20" Carrera Classic wheels and am thinking of getting them refinished. The color is Dark Titanium and color code is OC6.

Only problem is that OC6 is not an official Porsche color and I can't find matching paint in the aftermarket (even Dr. Colorchip).

Has anyone refinished these wheels satisfactorily and have any advice on paint to use?

Thanks.
