Thanks for weighing in on this. Is there something about magnesium that makes the pitting more dangerous, along the lines of the explanation posted by babymog? I would speculate that magnesium is a harder, more brittle metal than aluminum, and cracks more readily... And if this is true, where do Mercedes alloys fit? Those small oval 'holes' around the edges would clean up nicely in seconds with a blast of fine sand (#00), a major PIA to do manually.
