You can also try meg's colour boost, it is quite effective in removing light swirls and scratches, also beforehand you might want to clay bar or paint clean the car to get rid of any dirt in the pores of the paint.

With Buffing Machines, no doubt the safest method is to use a random orbital, using a rotary buffer without any experience will most likely make your paint worse than what it is.

oh and also this could probably be put in the detailing forums i guess
