I notice the can of Mother's polish in your first photo and I'm curious if that is what you're using to get a shine. If so, have you ever tried a buffing wheel and compound to get the same or better results? I like to use a bench mounted powered buffer and polishing compound. There are compounds made for aluminum, steel, chrome, stainless steel and non ferrous metals like brass and copper. It's much faster than hand buffing and smoothing the metal. I think you'd like the results.
