There's a bracket around the top tube with a hole in it. A bolt passes through the hole, to hold a doodad that the swing chain can be connected via an S bolt.
When the swing swings, it makes an awful squeak. I was originally thinking of spraying it with silicone spray, but then thought white lithium grease or powdered graphite would be better. It's metal on metal contact, and outdoors.
What would be the most appropriate lubrication to use in this situation?

Since this is exterior, and I'd be too lazy to oil it after the first time, I'd use grease. It's the preferred maritime lubricant, and that's good enough for me.
