Sanding Gloss

How much sanding should I do on a gloss? When to say when with the 400 and 600. Tanks.

…If you start with 400 = when the sheen is gone,and the surface is even/flat(as possible).600 grit = when the majority of the 400 grit swirls are gone,then polish.Herb

1st step…320-soft pad? 400 medium pad?? vice versa

…soft pads only,unless your gloss is really plowed.Herb
