I went with an earlier version of this Menzerna kit

You can't go far wrong even with the Menzerna 400 cut.
You would do more damage working a small area by hand than working on 1/4 of a panel with the DA.
The problem with white is identifying the worst swirl areas as their alot harder to spot than on black. Even with a sun lamp.
