For years now, I've been heating a pan over the Coleman stove, bicycle chain laying flat in it, and I melt paraffin wax on the links. It is solid at room temperature, so it collects very little dust. What it does collect is black wear metal, so, I scrape off the wax from the pan, between waxings. It really makes the chain stretch happen slower. No messy oil, but, it is the same thing that is in liquid Boeshield, if you want to put a drop of oil on the caked wax - it will eventually evaporate, and solidify. You can rub it on sheet metal, rusted or painted, and melt it in with just the sun, or with a propane torch - it protects forever, kinda. I just use holiday candles - candles make a great saw and drill lubricant as well; I suppose the canning wax would be a good option as well. Motor oil, in its early days, all came from Pennsylvania, Quaker State, Pennzoil. It came from there because the deposit naturally had high content of paraffin, and low sulfur.
