Most of the area of my floors is in pretty good shape. However, the stairs are pitted from bits of gravel in shoes for the last ~100 years. I have been sanding these steps with 36 and more recently 20 grit paper for over five solid days and don't seem to be clearing up most of the pits.
The steps look OK unfinished to the casual climber, but will the finish exaggerate the pits and make them more obvious? I'm looking for a way to bring this project to a close but I don't want to short change the work I've already done.
