Need someone to refresh my memory on the grit equivalents of the brown and green scotch brite pads. I know that white is about 1200, grey about 800. Also what do you prefer more, wet sanding or scotch brite. Thanks in advance.

This is directly from 3M:

7445 - White pad, called Light Duty Cleansing - (1000) 1200-1500 grit
7448 - Light Grey, called Ultra Fine Hand - (600-800) 1000 grit.
6448 - Green (?), called Light Duty Hand Pad - (600) 600 grit
7447 - Maroon pad, called General Purpose Hand - (320-400) 320 grit
6444 - Brown pad, called Extra Duty Hand - (280-320) 240 grit

(The value inside the parentheses is directly from 3M.)
