I may have jumped the gun on calling you a Bubba. I will admit that If I would have got a Black Bolt SKS instead of a silver bolt, I would have stripped the paint off, Unless it was a non-issued, matching one.
Anyways, I imagine it can depend on the steel used. But like mentioned, will tarnish very quickly. If you polish it, take a picture right after, and wait a day, you will notice a pretty big difference, it will turn into a dull gray and progressively darken after that. Maybe try a high polish blue instead?
