Restoring paint color tips?

Harbor Freight (snic) sells a decent variable speed buffer that works pretty good for the price, Dont get the fixed speed one, for a few bucks more the variable is much more flexible for fast cutting or slow polishing. Get some quality bonnets and name brand chemicals, McGuires or 3M. Keep buffer moving especially over raised ribs and corners, some compounds can cut very effectively over raised parts. Oh yeah, someone told me to never use silicon polish, like Nu-finish. Youll never be able to repaint the car due to fisheyes. Im sure a paint guy can elaborate.
