From my personal experience, I agree with Carl and Rick about Clean & Sheen. It is also designed to smooth out sanding lines from 500-600 grit sanding. It leaves, with enough spinner work, the equivalent of 1000 grit compound finish. FYI it is almost exactly half-way, in appearnace between a matte finish and gloss polish.
Clean and Smooth puts a 1500 grit smooth or matte finish on a ball, IF you start with a 1000 or better yet, a 1200 grit sanding, or dare I say, a Clean and Sheen'd compound finish. yet, if you apply too much pressure for too ling a period on a spinner, you will get an almost polished look to it. That's a sure sign you went too darn far!!!
