Pin holes in used bellows

[P Sanders]

In testing a newly purchased 8x10 (an old Deardorff) I found several pin dots of light leaks at the bellows creases and folds. Is there a liquid flexible sealant that can be applied to the bellows? I have doubts concerning black plumbers or gorilla tape.

Thank you for your help

Yes, what's suggested above will work, but after you fix one pin hole another will pop up since the bellows is probably on its way out. I used an old 4X5 years ago that had a few corner pin holes. I didn't have much money at the time so a replacement bellows was out of the question. All I did for a long time was after setting up and final focusing I would take my dark cloth and drape it over the bellows and tuck the extra under the bellows and between the front bed. I'd then pull the dark slide and trip the shutter. Worked extremely well until I sold the camera.

I do large and small bellows repair with 3M Type 850 black polyester tape alias "bellows repair tape". This ultra-thin tape is stronger and more durable than any bellows it is applied to. Expensive.

for that problem ,I'd use black liquid silicon and a small brush.

Neoprene glue.

Thank you. . . I never heard of liquid electrical tape and was researching black aquaseal (wet suit repair). Will buy both liquid tape and black silicon.

I paint the bellows with Puffy fabric paint, and if that doesn't plug the holes, I cover the area with book binder's tape.
