Bluing is essentially controlled corrosion, and in no time it'll lead to sporadic uncontrolled corrosion as you handle the frame and expose it to the elements.
Wax is the same story, you'll spend day in day out reapplying and cleaning in-between reapplies, it just won't protect the frame long term.
