I wetsanded, buffed , then polished my Miller (30 years old), and had very good results. Here's the steps taken & products used:
wet sand 1200, 1500, then 2000 grit. Next, using a 7" variable speed sander/ polisher with foam pad applicator and 3m "perfect-it 3000" liquid rubbing compound buff all necessary areas. I did the whole top of mine. Next I used a softer foam pad and 3m "perfect-it II Foam Polishing Pad Glaze". Lastly, a couple coats of your favorite wax & you should be good. A foam pad on a random orbital sander works good, or by hand.
