Letter 20092 Aging Magnesium [California]  +++ I have a pair of real magnesium automobile wheels, mfg. by American Racing from the 1950's. As you know magnesium turns black over time. I cleaned the wheels up as they were very stained. What I would like to know, is, how to speed up the aging process that turns the wheels black? I am looking for an even black color.
