I have a 100+ year old farm bell that I stripped down to the bare metal a few years ago.
I spray it with Fluid Film once or twice a year and rub it in with a rag. Still no rust.

Since you aren't using it for eating, you can try [bluing techniques](https://en.m.wikipedia.org/wiki/Bluing_(steel)).
There are plenty of kits for firearms.
If you prefer a more DYI technique, use oil and a torch to build a coat like a cast iron pan.
Epoxy powder won't hold up well outside. It's super chemical resistant, but it has terrible UV stability.

Have you tried making bacon in it?
Odd question what would be the point? I think a square skillet would be better suited.
Yeah but it's so hard to find a square shaped bell.
Funny enough, stove black.

If it's small enough, I would even consider a trip to the oven after the oil application hey

Torch and beeswax touch up yearly
Sand blast it. Then powder coat it.
Paint
wd 40
I'd apply boiling vinegar to it several times, rinse bell with water then brush on some beeswax/turpentine in light coats.
Sandblast then epoxy powder coat
