Not sure if this is relevant as it looks like you're planning to paint the wheel under the chrome clad covers?
I tried to paint the chrome clad covers. I spent HOURS scuffing the chrome to a haze and followed the directions for cleaning and degreasing before applying dupli-color primer and wheel paint. It adhered pretty well in the summer months with only occasional rock chips from driving on gravel roads (I really wouldn't expect any paint to survive this). However, when winter arrived and I pressure washed the wheel the paint peeled pretty bad.
Conclusion: I wouldn't attempt it again. For the time I invested I'd rather just buy some aftermarket wheels.
