dudley, I read the whole rim repair page thoroughly and the guy warns that this process only covers light scuffs and I think my two scratches are a bit deeper than that of this Porsche. From what I understand, the guy who is going to fix my rim, wants to wet-sand and then polish the rim. Have you (or anyone on this forum) ever tried fixing this "curb rash" on a rim yourself? If, so is it hard??
