I have some small spots on the mag elevators that need a bit of
touch-up. On the Aluminum I use a bit of Alodyne solution. Clean it
well, then Alumaprep and then repeatedly wipe the area with Alodyne
solution until it's gold colored. Then wash thoroughly.

However, I don't know what to use in the case of Magnesium. Same
stuff or what? Any socially acceptable suggestions?

Check with your paint supplier -- they usually have an excellent library
on preparations for using their paint systems with different materials.

Magnesium can be tricky, due to its affinity for the oxygen in the air.
