Porter Cable with Mothers?

[Murchie]

So all along i've been using the Simoniz orbital polisher. It gets the car shining but the swirls remain. And thats why i'm going to get a Porter Cable. Now would the Porter work with Mothers products? I have the 3 stage and if it will get the minor scratches/swirls out then that'll be great. If not i'll get the Menzerna or the Wolfgang stuff
. Or do you guys recommend something else?Also what pads do you recommend? The car in question is the one in my sig.

Thanks for your help.
