As for the Lake Country ThinPro pads, the grey is REALLY aggressive so I don't think you'll need that one. the orange is a cutting pad and the white is a polishing pad. My guess is you can get away with just the orange pads but you want more than one or two because trying to buff out large items like boats and even cars with only a few pads simply wears the pad out quickly from the heat, pressure and violent oscillation action these tools put the pads through.
