I croxed a balsa board this weekend and turned out nicely except for a spot where it seemed to have a clump. I used 600 grit sandpaper on glass like I would lap a stone. So I tried to lap it again and reapply the crox mixed with Fromm strop dressing. Now I have scratches on it. Should I just chuck the board and crox the backside of one of my English bridle strop? I would post a pic but, the scratches don't show up.
