Mirror Finish on D2

[Dan Gray]

Lynn, probably because the wet paper with lube is cutting much more, and the dry sanding wears down. Dry grit on the paper cuts much less with the used grit keeping the actual cttting particles clogged, too. You are actually doing more polishing as you continue to use the same piece of dry piece of sanding paper or cloth. You have broken and small particles mixed in with your regular grains when dry sanding. Wet tends to wash out the used and broken particles, as well as the removed metal particles.

John is right on with his reasoning, use the dry finer stuff last
