I have the Lake County 7.5" advance pads but I have a Black car and while the did an OK job, they didn't really remove the swirls and light scratches like I thought a PC should do. I would like to get a set of 4" spot pads, maybe an orange, yellow, and white pad. (I know some manufactures have different colors). Which pads are good to use? I may just do the whole car with the spot pads and save the 7.5" pads for when the car has less markings. Plus I have some Holograms that I need to remove on my rear bumper. Thanks.
