Hello there!
Thanks for such an informative post! I am glad that such things are possible.
Is Aquadag something you purchase or something you make? If you make it, what's
the recipe? Can it be done with conductive lampblack (which I just happen to
have...)?
Also, what's the recipe for this plating solution that you are using?
Thank you very much!
