  1. Maury, blackening metal can be problematic at times.  A few years ago a club member gave a demo/talk on blackening metal at a club meeting that I think would help out a little.  Once the part as been cleaned and degreased it was pickled in a hot Sparex bath.  According to the member this gave the part some tooth and allowed the blackening agent to work.  And he used Caseys Brass Black.  Since the stuff is a mild acid I think a long soak in white vinegar might do the same thing and be a little safer.
