Having a problem plating pewter
++++++
Can you please tell me what are the proper metal preparations in
plating pewter based materials? I really have a problem plating
pewter based materials because after acid copper, the result isnt
really good at all. do I have to do something first before acid
copper and nickel or gold plating? tnx a lot...I will really
appreciate your help.

++++++
Plating processes rarely can start with acid copper because it
will immersion deposit on most substrates, Earl. I am reluctant to
suggest that you try cyanide copper since I don't know your ability
to deal with it safely; but although the composition of pewter my
vary, I don't think you can successfully start with acid copper.

Try this: Clean, rinse, 10% flouboric acid, 1 minute, rinse,
nickel plate. Forget the copper.
