I should probably wait to take my calipers apart before asking this question, 
but I thought I'd ask 
now before the discussion goes stale. I hope this isn't a dumb question....

If the pistons are stuck in the calipers doesn't that mean that the caliper 
cylinders are rusty too. 
  I never hear anything about how to clean up the caliper cylinders. I don't 
think Nelson addresses 
it at Buckeye either. Bead blast, hone, resleeve ...???

Confused... feels like it must be a dumb question... Oh well.
