QUERY: gilding a plate

[Paul]

Jon and others
Thanks for the tips. You answered several other questions with your replies.
I do have an HVLP system, but used the old "high pressure" system before
that. I had good luck with bronzing  with it, but never attempted shellac.
I'm going to give the old method a try with the shellac and bronzing powder
and let you know the results.
