i can't speak for your particular film but i have used x-ray duplicating film (a reversal film) to enlarge negatives for pt/pd printing. That film is very slow. I use Kodak GBX (dental x-ray chemistry - dev - water stop - fix - wash - dry) and wash for 45min in a chambered print washer. I haven't used PermaWash and have not had problems. That film requires a red safelight. I'm sure there are various combinations that work. Find the one that works for you and stick with it. I would leave it in the hangers to avoid handling until dry and then preferably with cotton gloves unless you have a border that you don't mind having fingerprints on.
