Good timing... my Ikonta sprung another corner leak. I had used GE silicon and India ink, but it took about two weeks to dry... It dried flexible and held, but a new corner gave way.

I suspected it was happening so was guarding it from light wherever possible... Yet I got a little flare. I really must learn hold up to the light before loading each roll... at least with a 4x5 you can check with every shot.
