The cure for a dried coater
The ingredients in the coater consist of zinc acetate, acetic acid, and methanol. I had no methanol, but tried using one dropper-full of isopropyl rubbing alcohol 91%, plus one drop of acetic acid (indicator stop bath - be careful with that stuff), which I put into the container, as you see.
After a few minutes the wonderful perfume scent we remember returned, and apparently the acetate dissolved from its hardened state, producing the sticky spreadable consistency that you would expect. Glacial acetic acid might be better, along with methanol. We don't want our prints to turn purple. Unlikely. This concoction seems ok also.
On the left, a New55 dark sleeve with some exposed film in it newly attached to the metal clip from an Old 55 sheet sent in by one of several helpful people. More progress.
