I read somewhere about treating shutter curtains with Pledge. It seems to keep good curtains working well. It's made dried-up curtains supple again on several cameras. I first used this about 8 months ago.
The question: Is it a permanent fix? Do I need to re-treat the shutter curtain periodically to maintain the benefits?

Ive used it on two really old curtains that I thought I'd have to replace.(series b 3x4, 2x3 auto jr) So far so good, but its only been about a month. Even if it doesn't last, at least it will give you some time to order curtain material.....mines ready and waiting.
