Question: see any rust issues in the screws/holes after some months/years in the field?
I've been doing what Formidilosis listed, with the exception of nail polish on top of screws, for a long time. I think all of my rings have rusted screw heads. I'm assuming that it's accelerated by de-greasing everything but I'm hoping using nail polish as a final coat on top will minimize this rust......as is, I think the rust works well to help "lock" them ring screws in place so they don't loosen.
