I bought a Purdy 4.5" mini-roller today to help cut-in the ceiling for
the second coat. I expect to have to use a brush too, but it should
be easier after I get some paint on the stiple! The largest knap I was
able to get for the mini-roller was 1/2", but I am hopeful (I am using
3/4" knap roller to roll the ceiling). It will save hours of tedious
work if it works as well as I hope it does.

BTW, the Zinnster dries darn nice! Maybe nicer than I deserve! : )
All of my drywall and ceiling has one coat now, though there are still
other places to paint (door frames, door, attic door, etc.).

The following is my main question for today though:

I was picking at some dried paint runs, and produced
"holes"--even deeper than I may have expected. Then I tried some 600
grit Wet or Dry,
and observed that I could sand away paint runs without making holes. I
rolled some more Zinnser over the area involved to cover my deeds.

I intend to pursue whatever might need a little sanding, before I put on
the 2nd coat.

I noticed that some painters boast that they "sand before putting on a
2nd coat". Do they mean that they sand everything? Or do they mean
that they sand imperfections like I described above?

I never saw my dad sand any paint (expect varnish). I guess we didn't
know any better.
