I have been doing research, here and other places, and have decided that polishing is needed for light swirls and a deeper finish. I am pretty well set on einszett polishes as I have seen great results and will not be using a pc. Would you guys recommend Lack Politur (green) or extra paint cleaner compound (yellow) for a car that is religiously washed properly and waxed frequently with P21s? Any and all help is greatly appreciated!!
