I have a spot of casehardening that has worn and looks lighter than the rest of the frame. Anyone have any suggestions on a possible touch up that could be used to 'darken' the area? Cold blue that gives a 'brown' color would work perfectly but I don't know of such a thing.
I tried 'Plumb brown' on an extra screw I had lying around and to my surprise it removed the bluing and turned the screw pink (this was without heating). Definitely not a candidate.
Thanks in advance.
