Well you are taking it off
It only matters that it comes off not what its now useless body looks like. I use a standard metal automotive oil filter strap wrench. I sometimes leaves small indentions in the side of the can but it always comes off.

On my most recent oil change I felt my filter was never coming off. But, what Danny said worked - I held some constant pressure and it started to ease free.

just a thought, would it come off easier if the engine was hot?

The SAE standard for oil filters is 1.5 turns after the gasket touches. The gasket must meet the pulsator test at 1 turn for good measure.
Why don't we use 1.5 turns instead of this (silly) torque standard? Is there an aviation only oil filter standard? I think not, unless someone can quote a standard test number.
There is no more a difficult application than hydraulic or diesel lube systems due to the high dynamic pressures, they both use the 1.5 turn installation standard.
Added: Yes, Longranger it is 3- 1/4 turns not 3- 1/2 turns. Thanks for the save!

Hmmm... every oil filter I've ever changed says 3/4 turn right on the filter. I mark the rim wth a Sharpie, then hand turn 270 degrees. Never had a leak, and I only have a problem removing a filter when I don't use DC-4.

Dow Corning 4
Two IA/AP guys have recommended DC4 to me. I have some, and will use it in the future. It's also good for lubing spark plug wire ends before they slide inside the plug. I thought that was a bunch of hooey, but recently needed to replace a harness wire on my Bonanza because the silicone shielding was torn and grounding out, probably from spinning during the tightening process. Not hard to replace, but over a hundred bucks.
A tube of DC-4 is a lot cheaper.
I tend to trust one of the IAs... I think he's about 87 or so and has been doing this for quite a while.

I have one of Allan's oil filter wrenches, and it is GREAT.
But, it would be easy to over-torque during installation.
I prefer hand-tight. I mark the filter after slightly snug, and then turn 3/4 turn (270 degrees) or a bit LESS.
No leaks.
I am of the belief that over-torqueing the filters, and not using Dow DC-4, are the root causes of the issue.
i.e. : Put a little DC-4 on the gasket, turn it on by hand, and snug it up. Safety wire to make yourself feel good, and it won't leak, and it won't fall off.
Next oil change will be just as messy, but no problem getting the filter off with Allan's wrench!
My Two Dollars. And YMMV. Don't blame any leaks or stuck filters on me!!
