Personal preference really, different people will tell you different things..Go back to the home page and click on the car care section, theres a few discussions in there about which cut and polish prouducts people have used before, and what they thought of them.
But dont be put off by it, sure you can completely **** up your paint if you dont do it right lol, but with a bit of practice on some old panels, you pick it up in no time, and then you'll be confident to start on your own car..:thumbsup:
