=46or regular stop bath, sure. But these (the ones I got from the net) were
MSDS datasheets for _Indicator_ stop bath which, I would think, should
include some sort of indicator chemical. As you say, Kodak must be the
reliable source for this info.

Now's that you mentioned it, I wonder if citric acid formula (or in that
sense, any other stop bath formulas that use other types of acids) is less
likely to cause pinholes...
