For a new dull finish on SS what is the best grit and type ? I was looking at 320 aluminum oxide but I'm not sure if it is the right thing. I've always had someone blast things for me and I have rubbed it down with SS fine wool afterwards to get the desired effects. I've always gotten a little rougher finish than I wanted so I think they have used a rougher grit. I would like to get a smooth finish but dull.
