Not sure I am following, are you saying you expose the original blueing? Cause that would be cool!
No, what they did was sandblast the gun, then some kind of acid anodize that looks like a grey parkerizing.
Then, some concoction of printers ink, lamp black, xerox toner, or God knows what makes up the BBQ finish.
But, methyl hydrate loosens that concoction, so the black crud can be scrubbed away.
The original bluing was sandblasted away, leaving a mottled surface - not smooth like the original.
Cold blue doesn't go well with that grey anodize/parkerize whatever, so you have to sand, steel wool, and reapply cold blue a number of times before developing a nice new finish on the metal beneath.
