Mask everything! I think you might want to do a few simple thngs first like remove the lower cover panel below the steering column, remove the steering column top and bottom trim. Did I say mask everything.... then make sure you have the wheel clean and free of all oils, silicone, etc, otherwise you will get fish eyes. Paint it with several light coats allow drying in between as recommended by the manuf. Did I mention mask everything???? Maintain the proper temp..... allow proper drying time and a bit more. Oh ya and mask everything..
Why not just pop the wheel off?
my 2 cents
