I rescued a NIB S&W stainless revolver last Saturday at an estate auction. Unfortunately, the previous owner did not do much to maintain his gun. Spot of rust under the grips that I have been working on this week with a bronze brush, soft cloth, Flitz, and elbow grease. Should I get more aggressive with it (Scotchbrite pad or fine sandpaper with oil?) or call it "good enough" and leave it alone before I do more damage than good? I really want to get rid of what is left, but am concerned I may cause more problems with the visible portion near the trademark.
Here is how it currently looks and the second picture shows that the grips cover up the area completely. As you can see, the usual micro-scratches typical of stainless steel are already present.
What do you think?
