The OLD original formulated Aero Gloss from the 50's to Mid 70's was incompatible with current Brodak/Sig dopes. The stuff produced later than that is compatible. One can differentiate the two by the font on the cans of the "Aero Gloss" and the ingredients on the label.
If it mentions Tricresyl Phosphate it is the old "first generation" stuff.

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
