There are some great youtube videos out there as well. I had the opportunity to spend a couple hours with a guy who polishes stainless steel for a living. His bread and butter are old bel-aire's and earlier. When i was there he was working on the trim for a 40s cadillac convertible. Irreplaceable pieces, pretty rough shape. Dents came out with a pick on oak block, smoothed with a file, then sanded down progressively. His final sand was 3000grit wet mibro. Then he went to buffing wheels and rouge. he sanded everything 440 and finer wet. and in a straight line. when it was done, you could see yourself clearer than in a mirror. it was enlightening. he is a craftsman. and his work reflects it. after he was all done, he said it wasn't hard, but the key is to go step by step and don't skip any steps. Identical to prep work for a paint job.
