Disintegrating light seals are a fact of life with most cameras manufactured from the 1960's onwards. Here is a method I have used on hundreds of still cameras which is derived from my time repairing cine camera equipment. Arriflex, Mitchell and other film magazines use light seals made from lengths of wool, velvet or felt tape glued in place. This method stands up to the constant loading and unloading of the movie world often for years at a time. In your classic camera they will last forever. You will need a few common hand tools, some acetone, Bostic Clear Bond glue, Rubber Cement - I use Ados F2, 8-ply black wool (not acrylic!) and velvet tape. You will also need a well-ventilated space, plenty of time and old camera to practice on. Let's get started: 1. Cut a piece of paper to cover the film gate and attach it with Sellotape making sure that all edges of the tape are sealed to prevent the ingress of the old foam when cleaning.
