Makes perfect sense. The rust a given volume of steel makes is bigger than
the original volume. The pit pushes rust up as it gets deeper making the bump
in the chrome. As you start smoothing the first thing you will do is remove
the excess volume of rust leaving the pit full to the top with rust. If you
media blast or chemically strip the rust you will uncover the pits. Before it
can be chromed or much anything else all the rust must be removed from the
pits.
It's just an ugly problem without any easy solution that I know of.
We're very lucky that they weren't in love with pot metal trim like some other
folks. That stuff is a real bear.

Well the spots on my chrome appear to be external, not internal. Thus I'd be
grinding them "off", not grinding the surrounding area down to match.
Make sense?
