Rudy, I believe you inadvertently mislead the guy on the cobalt plating set-up. The work is connected to the negative (-) side of the DC power supply, not the (+). Cobalt plating has some characteristics similar to Watts nickel formulations. Nickel/Cobalt was briefly considered as a substitute for nickel electrodeposits many years ago when there was a worldwide nickel "shortage". Nickel plating additives could work. Postum (sic) and even instant coffee are known to have been used as plating "brighteners" too.
