a good kit for a variety of cars? i am about to purchase a starter kit that i can use on my 5 cars, they all vary on condition and paint. some are clear coat, some are european with metallic paint or whatever it is. some have lots of swirls others do not have swirls at all. is the optimum kit a good general kit? it includes optimum polish, optimum compound and optimum poli-seal and a couple wolf gang pads. will i need to buy other pads as well? long post, thanks for reading!
