Here are some photos of wet sanding and buffing. I played with 600 and 800 grit last week. There was still some residual orange peel that looked like dried soap bubbles. I went back to 400 grit, and that took me to a flat matte. So far so good. Then all the way up (600, 800, 1000, 1200, 1500, 2000).
Here is what 2000 grit looks like:
