Well I got a set of razors yesterday, and long story short I decided I would start doing a complete restore to one of the razors that had a crack in the scales. Its my first time ever restoring a rezor so im pretty new at this, Ive looked at the wiki link and I started out with a 220 grit M3 sand paper that I had in my garage, I'm an hour into sanding and it looks a world better than it did, but there is still marks that wont seem to come out with the 220, should I just use more elbow grease and do a bit longer with the 220, or move to an 80 or a 100, or just go down in coarseness to a 400?
