So any recommendations on how to remove the last stubborn vestige
of the old coating?

Should I just leave it and let the coaters blast it off some how?
or is there a more effective chemical bath I could try.

there is a small Ronchi image (73k) of the stripped mirror here

and a short but largeish (33M) video clip here

I can put up a direct image of the spots it that would help.

I use Ferric Chloride from radio shack. It costs a few bucks and you can
reuse it forever. When I've used it or seen others use it, it has striped
the mirror clean to the glass in all but one case. DON'T get it on your
hands, leaves minor skin irritation, I got it once, nothing bad, but easier
to wear gloves.

Good Luck
