Palladium plating question

Hello all,

I am trying to figure out how much yield I could get from a quart
(2.5g Palladium) bath. Now, I know there are so many variables that
affect the yield but I wanted some guesstimate numbers. We will be
plating earrings, pendants, and charms and on some occasions, full
necklace pieces as well as bracelets. This is mainly for tarnish
free coating purpose. We usually send our jewelry to get ecoated but
that is 2 days in transit plus the labor time which in some cases we
do not have the time to show to clients. My understanding is that
unlike rhodium or platinum, palladium does not require the nickel
under-plate which makes our lives a whole lot easier. We already
have the plating equipment for gold plating purposes, so we are
covered there.

Also, for an alternative solution (and much cheaper), we are looking
at the lacquer coating like the Midas Finish Seal Lacquer (Rio Grande
part number 335-123) or Midas Clear Lacquer Tarnish Inhibitor
(335-149. Does anyone have any experience with these products? I am
wondering how durable these coatings are. Will it be OK to coat
chains with these solutions? Any help will be greatly appreciated.

Best regards,
Dan Yokota
