Neither.I am a neophyte when it comes to polishing metal. I just used the 4000 grit bare on the surface. I feel like a fool here. Shouda asked for advise before doing this.
I doubt you hurt anything, just maybe a bit more work to get whatever level of finish you're looking for. With 4000 grit abrasive, you are polishing much more than grinding, so no damage done. Are you looking for a mirror finish or something less than that?
