DEAR TOM, Kodak publication J-1 Photo Chemicals does show it on Page 41. In an e-mail conversation a few days ago with Doug Corbin formerly of Kodak he still recommends it. I don't know if anyone has said otherwise. Perhaps Richard Knoppow can shed some light on this. CHEERS!

Is there a reference for this information?
