Light sealing not just need s removing it needs replacement Or light leakage will almost certainly result But if you clear the old seals and haven't time to replace and you want to load film just tape the camera up. It's fairly easy to do the replacement yourself If in doubt someone might do it for you I bought an OM10 from a dealer and he did the seals as part of a deal which was good

Post-it-notes, instead of masking tape. It works great, and seems to leave no discernable residue. In most major cities, you can find someone that will "CLA" and redo your light seals for a pretty reasonable fee. They have a shop, tools, parts, good lighting and the experience to do the job right. I've never had to wait more then a few days to get these little jobs done. For me it's well worth the money just to have a beautifully CLEAN and CLEAR view finder/focusing screen! Cheers.

Be mindful close to the eye piece got fluid in between the eye piece and prism and had to remove the whole top and eye piece to clean

I have an Olimpus OM 10 camera. The battery is getting hot and it doesn't last at all. Do you know why this is happening? Thank you
