[TheForge] cortisone and rust

[Clyde Wynia]

I sometimes get some rust washing off to bare metal if I forget to wash the
piece over night. I usually rinse off after an hour. At that time I have a
pretty good rust started and rinsing doesn't was it off.

Clyde, any idea of what would cause your excellent rust formula to 
seemingly work well, but then areas of the patina float off when sprayed 
down with a hose the next day?
It's possible that my preparatory alcohol flush  caused some oils to 
rise up out of the clean plywood the piece was set on for the alc scrub 
down...(that's the bottom surface that has the problem) . But that's all 
i can think of. It was thoroughly wire brushed.
