stock repair question
I picked up a rifle a few days ago that has a metal butt plate on it. so the butt of the rifle must have got wet at some point because the butt plate started to rust. the stock has a large dark spot from the rust leaching into the stock. is there any thing I can do to remove the spot? the stock is an old walnut stock and looks nice short of the spot so I want to try to fix it. any help would be welcome.
