One of the issues with sanding stainless steel is that from the factory it tends to have a pattern or scratches typically in a straight line. Of course any orbital or random orbital sander rotation is involved. I don't remember anyone mentioning it, but if you had a LS-130 and ran it in the "grain" direction you might be able to feather it in.
Search for "stainless steel" (including the quotes) and you should find a few other threads discussing sanding stainless steel.
