Wash the car, and then wash it again using a clay bar. Clay bar (miguires makes one) is important because it gets off the road grime. You dont want that junk in the polishing pad, making more scratches. I start polishing with the wool pad #1 from the kit and use the varible speed and go slow with light pressure. Let the compound do the work. Don't over apply the compound, splashes around to much if you do. This removes all the surface scratches and for my daily driver civic I stop there. Just hand wax it, dont bother with the final pads for that car. Looks great anyway.
For the chally, I continue with the other pads, and the finish is like glass.
Note: Both of my cars are 2 stage (color then clear coat).
I recommend you do an older car 1st to get used to it. You will be very happy with the results.
