Maybe that's why so manty mfr's have gone to stainless. Just a guess. If you brush it, it doesn't even scratch. The ultimate non-finish, finish. Imagine that.
All the SS guns I have or have had, have had a pretty fragile finish when it comes to handling and wear and tear, and are/were easily scratched/damaged. I actually got a number of them used, for pretty cheap just because of that. Having access to a bead blast cabinet usually cleans them right up, assuming you like a "matte" finish, polished is a bit more work.
Matte actually seems to show the scratches quicker, as the scratch is usually "bright" in comparison to the matte. In a pinch, the grey Scotchbrite pads can touch things up too, and matches S&W's matte finish pretty well.
A lot of people should not be allowed access to a flat bladed screwdriver.
SS also rusts if exposed to sweat and not regularly maintained. Its not near as bad as blued, parked guns, but it does rust, and especially in places like under grips, levers, etc, or up close to them. You really need to keep after it, just like anything else.
I picked this Colt up off someone at work going through a divorce for $200. It had bright polished "flats" and matte on the tops of the slide, front strap, etc. It was pretty beat up and pretty heavily scratched all over. I stripped it down and went over it a couple of times in the blast cabinet using glass beads, put a new pair of grips, and it came out like this. Wish I had a "before" pic, as the difference in what it looked like before was stark.
