Pro tip: A drop of lighter fluid on a stuck lens mount ring
Had a Canon FD 50mm f/1.4 come in yesterday, the filter ring was seized solid (like, no movement at all). Instead of grabbing the strap wrench right away, I put a single drop of Ronsonol on the seam and let it sit for five minutes. It wicked right in and the ring came off with just finger pressure. I was worried about residue, but a quick wipe with isopropyl cleaned it up fine. Anyone have a different go-to for this kind of corrosion?

Yeah, the lighter fluid trick works. My buddy had a stuck UV filter on an old Nikon lens. He used a tiny bit of WD-40, let it soak overnight. It came off easy but left a slight oily film. He spent more time cleaning that off than getting the filter loose. Now he just uses isopropyl alcohol and a rubber jar opener for grip first.

My dad used to swear by a 50/50 mix of acetone and automatic transmission fluid for really bad cases. He'd apply it with a toothpick, let it sit for an hour, and it always broke the bond. I mean, you have to be super careful with acetone around plastics, but it works.
