Ah yes, I refinished a Novus a while back. I takes an incredible amount of elbow grease to work with stainless steel. The difference between almost mirror finish and a true mirror finish is an incredible amount of work.
The most frustrating thing that I found was that all it takes is the tiniest invisible bit of grit to cause a tiny hairline scratch and then you're back to square 1 again. It takes a lot of patience (and a clean work area and a supply of pristine new polishing cloths too).
