Does anyone have experience with Griot's orbital buffer and polishes--compared to the Porter Cable 7424 and possibly one of polishes that Autogeek sells such as Pinnacle polish. I recently detailed my car with Zymol products (clay, cleaner/polish, and carbon carnauba paste wax). It looked pretty good when I was done but under certain lighting conditions, I can still see quite a few light towel and swirl scratches in the finish. I think it needs a slighty more aggressive polishing than I can do (or willing to do) by hand. I would like to achieve a near show room shine, if possible. Damn black car--I know, it's not a color, it's a job. It's definately a love/hate relationship!
