GP-1 has been around for a long time and recommended by
Kodak for protecting prints. It probably works fine on film
too. Kodak has another, more elaborate toner for microfilm
(GP-2). I think the only drawback to Gold toners is cost.
There really is not that much Gold in GP-1, I have not
calculated what it cost to make and use.
