As I said, I used Kiwi brown.
I won't post pics, because it's an outfit inspired by (and ripping off ideas from

) Aragorn's, not an actual Aragorn replica. In addition, the fine detailing of the finish and so on has been utterly distressed by years of abuse running around in the woodland.
As for the polish itself, no, it doesn't rub off. You work the polish in like you do with a normal pair of shoes. Use a cotton ball or a lint-free cloth. You then buff the resulting shine OUT by buffing with a soft-ish brush.
Don't use a proper soft buffing brush because it won't scratch the surface enough to dull it... unless you have many hours to spend doing this.
