I think people get tied up with the magic of oxide polishes. Without a superb pre polish the oxides are wasted. Also a number of people on the site have had contamination problems  that seem to me to probably be that the oxide brought up enough polish so that the bad scratches became very evident. Contamination obviously exists but it is an issue that many cutters can avoid by just getting  a perfect sequence leading up to the prepolish. If people took as much time trying to get the scratches out before leaving the 600 grit as they do trying to get scratches out polishing they would be happier and more productive.

What Frank said..., took me a while to figure out that 99% of the shape and polish happens on the course side. Without the prep, this game is not much fun.
