I have a 30+ year old stainless steel S&W Model 66 revolver that is in good working condition but has taken some cosmetic abuse over the years with dings and scratches in the metal. I would like to attempt to restore it without going overboard or doing irreversible damage. I have seen that taking 300 grit wet/dry sand paper to the oil treated metal by hand is a good way to remove the scratches that won’t simply buff out with a good polish. Have any NES members attempted doing this? My main concern is doing more damage to the metal, which would put it into a condition worse than the various scratches I started with. Any thoughts or experienced advise is appreciated.
