It's been my experience that Protek and Leather key bushings are not an optimal
comination. I would opt to polish the pins well, and coat them with Proteck,
but be sure not to let any proteck soak into the leather bushings. Seems to
develope a squeek after some use.

If the leather bushings are "glazed" from use a light brushing with a
fingernail file might be helpful, followed by a quick and light squezze with
your easing pliers.
