Any good ideas on how to restore faded black anodizing?

My 2006 H16 is practically brand new (hardly ever used since having a baby), but the black crossbars look like an 80s beach boat from sitting out in the sun for the past 3 years.

As an aside, I don't recall the black anodizing on my last two boats looking this bad when I sold them (at 4 and 5 years old, respectively).
