       Magnesium will corrode very quickly with no protection.  I once had a 
set of wheels stripped and they turned green before I got them painted.
       I would go with powder coating for the longest life.  You may not get 
the exact factory shade of silver, but you may like the color you get better.

       This past weekend I was racing at Omaha.  Jack Beck looked at my Alfa 
spider and noted a small crack on one of the Campagnolo Daytona wheels.  He 
said that magnesium gets brittle after about 20 years use.  So inspect your 
wheels carefully.
