Year ago I did color slides using SS reels and never had to take the
film off the reel to re-expose it. One just rotates it about 2.5 ft in
front of a 250 watt photoflood bulb for a minute or so.

Most of the iron remival products which use dithionite form acidic
solutions
when dissolved, usually sodium bisulfate is present in the powder
mixture.
I've used the earlier Kodak Kit intended for Panatomic-X and found it
convenient to do all of the processing with solutions, avoiding the need
to
remove the film from the reel for reexposure then reloading it for the
second development. This obviously is a personal preference and not an
insurmountable hurdle.
