Bostich and Sullivan carry a bellows repair kit. I have used it to paint an entire Burke and James 5x7 bellows and it works just fine now. Give it a few days to dry and a light dusting of talc then blow off the remaining talc and it doesn't stick.
hi donald -
equinoxphotographic also sells bellows repair stuff.
i haven't used either brand (B&S or EP ) so i can't tell you
which is better/ worse ...
