I have an 04 zx 250 that i just bought two weeks ago, the more i look at it the more i notice areas that the sun didnt hit are silver and the other areas have a yellow or green tint. I have tried 3m's fiberglass restorer and wax with a crafstman orbital buffer but only shined it up instaed of getting back to silver,i am hoping it's not a wet sanding job. any ideas?
