The reward for all that rock rubbing can be taken from watching the stone come into itself. At the start, this travertine can look more like rotten chalk than real stone. But as you care for it, it reveals its beauty. It's as if you're helping it get ready for a night on the town, which a few centuries of polish may seem like to something that came together at the bottom of a lake nobody's seen since the Trepidatious era.
Today I hope to move on to 80 grit. I won't get to wet sanding until the weather turns too cold for wet work.
