I use coarse med and fine buffing wheels with the dremel if I need to remove or minimize rust or pitting. I use felt buffing wheel with emery rouge to remove water marks and patina. Just be careful and make sure you arent heating it too much. I dip in water often as I do it with a bucket handy. Never had a problem even at high speed. Just dont rush it. Hand sanding takes a very long time. If you have it then by all means. I would start at 600 and up to avoid too many scratches that will show up when your buffing.
