This is a copy of a post I made to the list in December 2003. I have used it successfully for sealing small pinholes. Clifford. Somerset UK.
Copy. An old recipe for filling pinholes can be made from lampblack, rubber cement - the kind found in cycle repair outfits - mixed with petrol ( known to some people, I am told, as 'gas':-) The amount of lampblack you will need for such a repair can be collected from a piece of glass held over a lighted candle. The glass makes a useful mixing palette. The repair will dry flexible and *non* sticky. I promise!

These pinholes are really tiny. Light coming through them does not get
directly to the film as they are at the bottom of the folds. Incoming light
will have to bounce off the inside of the bellows first to reach the film.
So we have lots of very low exposures, similar to a very small pinhole
camera apertures, and most of it absorbed by the inside of the bellow walls.
The effect seems to be minimal.
I didn't even notice them until sticking a light bulb into the camera,
sealing it light-tight and investigating it in the darkroom. I suspect that
many view cameras have this 'problem' and never causing an issue.
I just can't live with the thought.

Ralph,
Another option I have tried is the black neoprene stuff they sell in diver
shops, which they use to repair diver/wet-suits. I had limited succes with
that though..I am realy surprised about your observation that these pinholes
did not interfere with the actual exposure! Maybe I have been to hasty with
replacing my Toyo Field 810M which was realy puuctered with a lot of
pinholes..;-)..
Best,
Cor

Disregarding the other possible uses of it, it can bethin yet strong layer, and gives sufficient "density" toreduce lightleaks significantly. Follow dirctions in the pack to get itnon-stickyafter drying, or your bellows will sick together into onemassive lump.bellows repair -
Don't ask me how I got the idea of trying this stuff for<info@xxxxxxxxxxxxxxxx>please :)

On second thought, I will attempt a repair, what the heck,with thatfor these bellows if I have to buy a new one anyway.
I did some research on Elastoseal. There are many productsnothing inname in a variety of spellings (Elasto-Seal, Elastoseal etc), butcompound! Any ideas?Germany. I'll try some other rubber-like flexiblesave some cash

Ralph, pinholes in the bellows can be a real problem! The ideal solution is to replace the bellows, but a repair willHome Depot)and extend the life of the bellows. One way to take care of pinholes, and also to repair big holes etc, is to get some black rubber roofing primer ( Snow Roofing Systems Elastoseal -camera thoroughlyand paint the inside of the bellows to seal the leaks. Use a foam brush! A conventional brush will develop little crumbs of rubber that will come off and stick to the cloth. Let thepowder anddry with the bellows extended ( several days to a week or so depending on humidity) so that the bellows do not glue themselves together. If still tacky, lightly dust with some talcumrubber finishvacuum out the excess or give a thin coating of the blackcoat.
The Elastoseal is a water based neoprene emulsion that drys to a flexible rubber film. Also good for waterproofing darkroom sinks. They also make a white and black top coats that work in darkroom sinks.
