Yes, I do allow it to come to room temperature before coating. The
instructions in May/June DCCT say "NOTE: This amount of Sensitizer
should be stoppered and refrigerated. It should be enough to coat
hundreds of 11X14 sheets." At least the last sentence is correct - I
have enough to last quite a while. One reasonable suggestion was to
filter the solution before coating. Does this sound
reasonable/necessary?
