Place your car in the shade, or wait until the weather becomes more moderate or mild. Direct sunlight or heat can damage the paint when chemicals are on it during the buffing process.
Wash your car thoroughly. All dirt, dust, and other foreign materials must be removed from the car before you begin the buffing process. Leaving any dirt or dust can cause scratching to the paint.
Cover all edges of your car to protect any area of the cars that you do not wish to be buffed. For example, you should tape the outer edges of all the car windows.
Apply your buffing compound to your towel and begin buffing the paint on your car using circular motions. This step will take a significant amount of time and strength as you are trying to literally remove the top layer of "damaged" paint from your car.
Apply your wax compound if you intend on maintaining the new "buff job" you have completed. This step is not necessary but highly desirable (especially if you already spent a significant amount of time buffing your car).
