For my car I use a non-water emulsifier, which is something like the spray and go stuff, it takes off small bits of dirt. I then use meguairs pure polish (7) and sometimes I use a little bit of the scratchX. I place them directly onto the car and rub back and forth, then take another towel and wipe off. The more you do the better it looks. The big thing that can and does go wrong is that the towels get dirt on them, and going in circles will swirl the dirt around. Make sure to have plenty of layers on towel between you and the paint so that there is more even pressure. Finally, once the car is done, you will notice dust on it, especially if it dark. Do you garage the car? If not I would recommend a car cover, only about $40 and it keeps the car much better.
