I was wondering if anybody ever uses any sort of lubricant on their hinge pin? On my Ralf Aust, I have been taking extra care to ensure that water does not roll down the tang into the hinge pin. I feel I have been doing a good job in that regard. But has anybody put a bit of oil, grease, etc along the pin to protect it from a wayward drop or two from getting in there? I was thinking of a tiny dab of white lithium grease just as a water barrier.

The scales are the factory plastic scales so I have to be careful on my choice of lubricants. That's why I am considering lithium grease as it does not soften plastics.

As always, any advice is appreciated.
