Took apart my rifle bolt on my old CZ to clean it the other night... put a few of the rusty bits in the sonic cleaner... and forgot about them!
It's all nice and clean now, and still works obviously, but would be nice to restore it properly - does anyone have a proper blueing kit I could use or pay them to do it for me?
Otherwise is there a cold-blueing kit that actually works?!
Thanks in advance,
