I thought Alodine was for aluminm, not steel. And my bottle of Alodine 1201 says "Chemical Coating for Aluminum" on it. Right now I have a piece of 4130 out in the sunny front yard that I mist every hour or so. One end is bare, and the other end I waxed with Blue Coral Poly Sealant. That'll be a data point after a few weeks, but so far one end is rusting, and the other looks new...
