I sanded a name off a bow I bought, and had to sand right down to the bare wood before the name came off. Believe me, I didn't want to do that, but once I started, I was kind of committed, since it would have looked worse if I had stopped when the name was halfway sanded out.
Anyway, it left me with a light spot where the name was. I refinished over it, and the new finish blended in fine with the old finish, except for the light spot.
I would have to refinish the whole riser now to make it any better, and I wouldn't try to do that myself. I could send it back to the bowyer to refinish, but it's really not that big a deal and I guess I'll just live with it. I like the light spot better than I did the name, so I guess I'm not sorry I did it.
