Dull black parts when taken out of nickel bath.
I'm getting dull black spots on my nickel plating that are impossible to buff out? anybody know what they are.I,ve double checked all my settings (amperage,temp).The part is fully polished before it goes in bath but when it comes out its shining on one side of the piece and has random dark dull spots on the other.I have stripped it several times and started over with the same results.Help!!!!
