Astro Black, tough to keep clean not garaged?
 

How tough is this color to keep clean? This may be a daily driver that will reside outdoors. Silver is so easy (pure or dark), but I really love the look of Astro. Of course, on dealer lots, it's easy to see nearly every spec of dirt on it, not quite as bad as gloss black would be, but wow what a stunning color.

So Astro owners, how tough is it?
