By this argument, a layer of varnish would be also a problem. The main
problem of aluminum is in the connections with other parts, where the
oxide causes bad contacts. Aluminum has also a great tendency to flow,
and so even if you make connections with tight screws and pressure 
washers, after some cycles of thermal expansion the connection comes
