    Yet another Rubberized FPS recovery technique

    Wanted to share a new thing I tried. Hope it’s not heresy or old news but I stumbled on this while trying to do the acrylic resurfacing technique but wasn’t sure how to soak the curtain in paint thinner in order to scrape it clean first. Turns out you can kind of reliquify the rubberized coating in place and it’ll redeposit in the cracks and be light tight. Here’s a unprofessional little video:https://youtu.be/I8Cz3pnuKRk
    Also sorry I’m realizing that might should have gone in DIY

    Moved, thanks! --Oren

    For future reference, can I recommend that you change the title to include "focal plane shutter"? I had no idea what FPS (frames per second?) was until I read the text.

    So what is actually the working substance in your "Lacquer thinner" ? can't read the small letters from your film.

    ...did it dry fully or did the rubber become sticky?

    I used klean strip laquer thinner although I assume any strong nonpolar solvent might work. MSDS says it’s about 1/3 each methanol, acetone, and misc alkanes. Once it evaporated the rubber was not sticky. I applied a lot of pledge to hopefully keep it from becoming too dry and cracking along the previous faults. I will report back in a week or two once I get the shutter reinstalled and try it in the field for a bit.
