Sorry for this late bit of wisdom, probably not relevant to the situation now, but just come across this site today and felt that I had to comment on this.
You don't really want to use alodine. There is a treatment called magnadine specifically made for magnesium. We get ours from Aircraft Spruce and Specialty, I know its available elsewhere also. You need to be really careful with magnesium, and especially magnesium aircraft parts, due to the high susceptability of corrossion. I am an aircraft mechanic, 16+ years now, and have seen a good many magnesium parts scrapped due to incorrect processes and procedures. Mainly wheels, but other items as well. One more thing, just a word of warning, anyone dealing with aircraft parts, be careful. If something happens, and it somehow can be traced back to something you did/applied, whatever, you can be held liable.
