I did mine 5 years ago. Cleaned them, light sanding to smooth, then sprayed with High temperature paint from an aerosol. I used Kurust before spraying. I masked off the area round the studs and wheel contact in the centre as I didn’t want that area painted.
The paint is from either Halfords or Frost ( can’t remember which).
