I pick up Joseph Elliot razor from e-bay couple days ago. The razor have horn scales (I do not have idea what horn is it) which are in good condition, there is no cracks or nicks but surface is little bit rough so I think about polishing them out.
Which way to do that?
Sanding with dry/wet paper (what progress to use)?
Sanding with compounds?

...or something else.

Also is it possible to varnish horn, I am not so familiar with CA and Epoxy finishes so I would rather not to do that.
