Damper lever felts, dents in

[Isaac OLEG]

You can found little abrasive rubber wheels that are used in Jewelry.
In a Dremel tool they allow to clean and burnish at the same time any
rough metal part (or wood for that matter)

Not really expensive if you find a professional supplier for
jewelers - select different sort and make experiments, I have some
yellow ones and white for the thinnest work, gray or brown are more
aggressive. They hold relatively well in time.

And I bought lately a suspended flex from Dremel, not so expensive and
not so professional, but it will do the trick I hope.
