220 is too rough to paint basecoat clearcoat over,or for that matter really any paint,well you can paint it but the scratches will show back up....the way i did mine was grinded them down really flat and smooth,and filling any airpocket holes with fine body plastic, eventually sanding with 180 and coating with a special raw plastic/rubber specially formulated adhesive promoter before priming them,then sanding them flat once again with 320,sealing them with PPGs dp series epoxy primer/sealer,puttin 2 coats of black basecoat and then 2 coats of PPGs clear...they look like 2 black mirrors in between the chrome coil bracket........so thats how i would do anyones, and thats why i would hit some one off that walked in off the streets that i dont know for $200:up:
