Spent 2 years pulling lens rings with a rubber strap, then a retired guy in Dayton showed me the freezer trick
For the first couple years at my bench I fought every stuck filter ring and lens name ring with a rubber strap wrench, and half the time I would slip and gouge the barrel or crack the ring. I figured that was just part of the job. Then about 8 months ago a retired repair guy from Dayton named Walt stopped by my shop to pick up a body I had cleaned for him, and he watched me wrestle with a seized filter on a beat up 50mm for like 10 minutes. He asked if I had tried the freezer, and I kind of laughed at him. He said he used to do it on every stiff ring back in the 80s, 20 minutes in the freezer on a ziplock bag, then a hair dryer on the ring only for 30 seconds, and the aluminum shrinks off the glass just enough. I tried it that same afternoon and the filter spun off with almost no force at all. Now I keep a little freezer box next to the bench and I have not touched the strap wrench in months. Does anyone else use temp changes like this, and do you worry about condensation inside the lens after it comes out?

How long do you let it sit before it warms back up?
