 If you must paint your anodized parts, just wash and dry them thoroughly to
 remove your greasy finger prints so the paint will stick.
 
 Painting is sort of gilding the lily, however, since an anodized finish is
 quite corrosion proof. Plus, it adds weight and you have to mask off holes
 and bearing mating surfaces. >>

A question to all... altho it doesn't look like a question.

I was under the impression that anodizing stress prone parts was not allowed. 
The reason being anodizing parts could mask cracks. In those prone areas, 
alodining/painting would be the prefered method of corrosion resistance. Is 
that something I dreamed or is that correct? I know NASA anodizes a lot of 
their stuff. I just don't know the purpose of their use.
