Polish is OK with dry flow.

Main thing that polish affects (vs. just smooth)--is heat transfer. It
reduces it significantly--both by reducing surface area and by reducing
radiation (emmisivity and absorbtivity are both affected).

Work down through grit roll grit sizes and then Brasso on a felt bob to get
a mirror finish.
