fparnold, Arentz reccomends Chrome Potassium Sulfate, I did not have this so I just used the hardener that comes with the Kodak rapid fixer since I never use it in the fixer. It worked like a charm, but probably left the paper acidic. I did not test it since I am only trying stuff now, no need to worry about permanence at this time.
