Title: Advice sought - Bellow pinhole leak repair
Post by: MJL on February 02, 2021, 09:18:14 PM

Does anybody know a better way to plug the pinhole leak in a bellow other than black paint?

My Polaroid 110B bellow developed pinhole leak on some of the corners.  I used matt black art paint to paint over it from inside with some success.  However, the pinholes return after a few fold/unfold action of the camera.

Is there is an "appropriate" way to stop bellow leak?  Much appreciate your advise or suggestion.

Look for liquid electrical tape.
It's a black paint that remains flexible.
Plastidip would also possibly work...

You can glue a small piece of light blocking fabric over the bad area.  I’ve scrapped an old changing bag to do this.  I used contact cement.

Thanks Francois and Bryan!

I don't have dark thick fabric on hand so I bought a bottle of liquid electric tape.

Keeping my fingers crossed - not sticky. ;)

I could mail you a piece of fabric if you want some, send me a PM if your interested.
