However, notice that on at least one of the front calipers it looks like the anodized finished on those is also wearing off. On one of the rears, you can see the bolts are fine and the finish looks pretty good - but it's starting to smear around some of the edges.

I dunno. The car is 6 months old. The more I think about this- the more I question the quality of the finish.
I would think the anodized finish would hold up better. Bummer

I think prepping and then zinc spraying your bolts will solve the rust problem as long as you don't have to keep removing them. That might be a small issue for the bridge bolts.
