I just did a fixit on a leaky Agfa bellows with some rather promising looking stuff called dimensional fabric paint from a craft store. Brand name is Polymark. It dries glossy so a few dabs on the outside corners aren't obvious. I did the big application on the inside and according to the instructions this stuff is machine washable after 72 hours so I'm thinking it would have to stay flexible. Temporary I know but worth a try.

My bellows repair experience has been limited to pinholes in the corners which I repaired by pushing pins through the holes , opening the back, and coating the pinpoints with black silicone rubber (RTV) and then pulling the pins back out thus plugging the holes. I left the camera open 24 hours to let the rubber cure. so far it has been successful. Let us know how your system works.

Fabric paints, or should I say some of them do work very well. My original examples here in UK were a bit hit and miss, but Jon Goodman sourced me a bottle that works brilliantly.(Have not got bottle to hand at moment but will give details if required). Unfortunately this brand does not seem to be available in the UK - probably not looked hard enough.

All I will say is that the paint seems to be more durable where it is applied over actual fabric strands and not a coated bellows surface. As Harv says it dries to a nice finish, so I painted the whole of the outside surface of a small bellows - worn corners and undamaged bits - as an experiment. The result looked stunning, but after a time the paint on the undamaged areas started to lift in places. The damaged corners remained and still are light tight. This could be due to the initial preparation/cleaning being wrong or insufficient.

I normally apply the paint to both sides of the hole/cracking and do it 'wet on wet'.

another product that works well is liquid latex. It can be bought on-line. just search for "liquid latex." But a warning. The supplier will probably be a sex fetish shop, apparently some people like to paint this stuff on their bodies.
