I looked into this a bit, and now camouflage all of my bolts. Apparently etch priming has potential to de-passivate stainless steel making it more susceptible to corrosion. However, the consensus seems to be that rattle can etch primers are so pissweak that there will be no significant effect. I've got etch primed hangers which have been out in the world for over ten years without any signs of corrosion.

There are some newish powder coatings which have unbelievable resistance to mechanical abrasion. As long as you're doing a decent sized batch, it would be a pretty affordable and very long lasting option.
