thx! To do the whole car you need a minimum of 2 pads of each color except for blue which is a sealant or waxing pad. One of those will be fine. Since you stated you dont have scratches that bad then i suggest 2 orange, 2 white, 1 black, 1 blue for your first purchase. If i were you, I'd get 4 orange, 4 white, 3 black, one blue which makes 12 total pads.
