You were 100% right. I did what you suggested. No more rust, but
the
surface is dull grey. I was kind of hoping that it would become
shiny,
like newly ground/sawed iron. Any way to get to this point? What
is
that grey coating?


The grey isn't a coating, it's the iron/steel surface with the
pitting from
where the rust was. I quite like the finish but if you really want
to get a
shiny finish you'll have to resort to old fashioned polishing
methods.

Nope. The dark dull grey stuff was black oxide. I removed it by
running a wire brish very briefly. (less than 1 minute). Now the
surface is very pitted, but actually reflective. I will post photos
soon.

Ig,

The wire brush is polishing the steel which as Mark says is grey due
to the surface texture at a microscopic level. The wire brush is
changing that texture by smearing the highs into the lows.
