Welcome to the forum. This is probably not the best thread to ask, since it's not really about what you're asking for. You should try posting your question over in the "Auto Detailing Forum" section.
Have you tried Meguiar's new M105/M205 combo? They used it in the detailing class and it worked really well in cleaning up the paint of oxidation, swirls, by hand or DA. Based on what I saw in the class, I already got some M105 and I have M205 on the way.
