I personally like the white curved CCS pads, and it can be used on the PC, or rotary. What color is your car, and how scratched however depends on which product you'll want to use. If you have heavier scratches, I would use orange ccs pad and Super Intensive Polish first on a dark colored car. If you have a light to medium colored car, you could use Power Finish with a green CCS pad on your PC as a one step. Best of luck.
