what is the best way to repair some minor scratches on the edge of the rim. They aren't bad. no dents --just scratches

 

Depends on what they're coated with. If it's a clearcoated rim (most OEM rims are) and the scratches are light, use any normal automotive scratch removal product. A light rubbing compound usually works best, just don't over do it.

If the scratches are real heavy, there's no easy fix that I know of.
