Fixing paint on outside mirros

I'm cleaning up my white 04 Prius. Have a friend who's going to give me a hand in polishing/waxing to protect the paint. However, he said my outside mirror paint was gone, though the rest of it could be revived. He suggested plasti-dipping it black, but I don't like the look of plasti-dip much, and I don't think it would complement the rest of the car. Anyone have suggestions on fixing the outside mirror paint? I've considered just buying a similar white paint and dousing them, since it wouldn't be immediately noticeable I don't think. Buying new white covers is $60 for both, hoping to spend less. Any touch-up paint that can be applied to the whole thing that isn't expensive?

 

Wow that looks great. Did you end up clear coating them? If all you had to do was sand them down I might give that a shot this weekend.
