Decide whether to use Orbital Random Dual Action Polisher or hand polish with a soft cloth. Faster results can be obtained with orbital buffer, but keep in mind that it is more difficult to control the finish of polish removal. It can also cause deep scratches if there is any dirt or debris between the buffer and the vehicle. If you use a orbital polisher, use it on the slowest setting available to ensure you don't remove too much paint from the car. Use hand polishing techniques for better control. Applying car polish by hand with a soft cloth takes longer but gives you more control over the process. It is also cheaper than orbital buffers.
Thoroughly wash your car. If there is any dirt or debris on your car, polishing will grind it down to a smooth finish. Before you start polishing, make sure the car is completely dry.
Apply the polish to a soft cloth or polishing pad and wipe it across the car in a circular motion. If you're using a orbital polisher, turn it on after using the pad to rub some polish on the car to prevent splattering. If you're only working on scratches, put more pressure on the scratched parts of your car. Gradually reduce stress as you move away from it. This will help the newly polished area blend in with the rest of your car. If you're polishing the entire car, work slowly, 1 small section at a time. Use plenty of polishing paste and take care to keep the cloth from drying out.
Continue to rub or polish the area in circular motions until the polish is completely gone. Completely work on one area before moving on to the next, so that the polish doesn't have a chance to dry on your car's surface before you wipe or rub it off.
