Mark, You are correct. Alodine is for aluminum and magnesium. I'll need to run over to the shop and get the name of the stuff you use on steel, it's a clear blue liquid if that rings a bell. Sorry for the confusion.

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...
