The film was getting wrecked winding back onto the reel again (wet reels?). More damage getting done so I'm cuting them up and storing them away in darkness.QUOTE]
Are you referring to refixing? If so there are two choices. Let the film completely dry and dry the reels as well and then rewind or simply drop the film alone into a bath of fresh fixer for say 2-3 mins and swill the fixer around as you would with wetting agent.
If the film isn't properly fixed then I don't think that storing away in darkness is going to help. Yes you can over fix but it takes a long time to do so or at least much longer than a further 2-3 mins of fresh fixing
