Personally, the use of quench oils used in heat treating also works well. It is typically a high grade paraffinic mineral oil, with oxidation additives added for this severe duty. These can be obtain

anodizing is probably the best thing to do. Alodining is also effective, and there are several types of brush on alodines. You can get pretty colors too - for instance the bright blue of TV antennas
