Painting Magnum Road Wheels Black?

I like the brushed finish, seems to match the "spokes" better than chrome or polished. Do you happen to remember what the width on those are? I need to get some for my Road wheel set.

I was referring to the wheel. I do have bright chrome trim rings on them. I don't recall seeing brushed finish trim rings that would match that portion of the wheel but... maybe with the right brush it could be done ?
