I am flabbergasted with the coating machine pics posted previously. So, I was wondering if anyone know where one can get clear base (precoated or pretreated to accommodate the gelatine). I have used polyester leader after treating it with NaOH and the results were not as good as using old film. The problem with old film is that I was never able to remove the old emulsion completely with Na hipochloride without scrubbing. My dream product would be a pre-coated film leader (with pure gelatine). Does anyone know if such a thing exist? Many thanks!!!
