Trading Flaws

Generally, resurfacing freehand will decrease radial flux (grooves and bands) and increase rotational flux (low and high spots in rotation).

There is some sweet spot to be find where you've removed most grooves and glazing, but haven't introduced much rotational deviation.

The Doing

The outer and inner lips need to be removed with a grinder first.

My hunch is that it's more important to remove glazing than to remove bands. Glazing will lead to uneven wear, hotspots, and pulsing. But a new pad will conform to light banding.
