I am not familiar with the Porter Cable orbital polisher specifically, but I prefer a regular buffer over an orbital. WEN and Milwaukee are two good ones. Turn the speed down, and pay attention to what direction the pad is going. In other words, hold it in such a way that the pad is always going from the surface and off the corner- such as doors, hood, etc., rather than the pad hitting the edge first before it hits the surface. And like mentioned above, for polishing, use the "egg carton" type foam pad- especially on dark cars, as the foam "bumps" will not put swirl marks in the paint. Polishing and buffing is something that literally takes hundreds of hours to master. I know you are probably thinking of just one car (yours), but after awhile, you will know what you can and cant get away with by the type of vehicle and paint you are working on.
