Grey stainless compound (SCR) is usually used with a Dico spiral stitched (firm) buff wheel.
Dico grey compound has a good amount of "cut" yet also produces a nice shine ("color").
For the finset finish that you can "see yourself in", follow with a white (or green) rouge on a cushion sewn or flannel type buff.
Packaged in resealable clamshell to keep your workbench organised.
