i use 3M glaze polish, with an 'eggpad' buff (which i go over by machine) takes care of swirls
then handpolish with meguiars 'next gen' polish using one of those round applicators, then polish off with a microfiber towel. this gives a nice shine
comes up great
only thing is i dont have a very good buff, just a cheap ryobi that has 2 polishing speeds, too slow and too fast lol
