My 615 mandola has a soft finish, and within a few days of getting it, I was wearing through the place where my fingers touch when I pick (I know, I know, I shouldn't drag my fingers across the mando's surface, but I do).
However, not a major issue IMHO. As Tailspin suggested, I just pretend I'm Sam Bush or some such...
