Hi, Lee et al
“The very best treatment” I don’t know, but Rhodium plating is
well appliable also to Starling Silver. Here we’re used to do it
also before making molds : we treat the pieces of model that way
(after we polish them) in order to have the wax patterns
fabulously smooth. Then tumble the casted pieces. The result is
very good and we can save time and superfluous efforts.
