Friction in leather keybushings

[Newton Hunt]

Hi Ed,

I have tried a bunch of metal polishes and have found that only FLitz, of the
ones available to me, works the way I want.

You will not be able to see the corrosion with a magnifier, it can only be seen
with a microscope but when it is there it acts just like sandpaper, which does
not bode well for friction reduction.
