I'm not sure about the metallurgy content of those cases, but I would at least paint it with SOMETHING to seal it up. The aircraft paint you mention sounds like a good idea.In case you are unaware,one of the reasons magnesium was dispensed with in wheels is because of their fondness to ignite when a tire would blow out and they would drag on the roadway/track. They do also want to return to their original form. It use to be that magnesium was 'farmed" from the oceans, but there may be other ways now.
