Re: Need help
gt_terje,
Wow, that is weird, but kind of cool looking at the same time.
Were you plating on aluminum, steel or pot metal? Looks as if there may be some particulate contamination in the bath or a piece of foreign matter lodged in the actual work piece. Zinc will sometimes leave a black, smoky residue similar to this one.
Have you tried to buff it out? It may re-plate better after buffing, cleaning and activation.
Keep us posted on the outcome of this one.
