soldered plated jewelry, the plating has generally burned off
that area, whether I protected it with flux or not. So I do what
I have to do, polish it up, and send it off for re-plating. Let
me know if you need names of platers. (They’ll polish it,
too…and even finish fixing the dent if you want to
FYI: with jewelry, you can often avoid replating if you or a
friend has a Sparkie to replace the post or whatever with.
