I thought of trying tin solder w/tix flux to simply fill the pits
Linda, the old saying been there done that, put the tin solder in
the trash can. Even if you get a good solder joint or fill in the
pits the solder will "disolve" its connect to the sterling silver
and fall off and leave a pitted area. The two do not mix.
In my own trial and errors filling a pit with any solder will not
work. You will still have evidence of the solder, of course you
could texture the area or silver plate.
