Keep in mind, if you are looking to polish to a full mirror finish, you will need to do all 3 stages of polishing wheels. You cannot go right to the final step and expect a full mirror shine. Also, if your part has existing scratches or a sand cast finish they will need to smoothed out with flap wheels. The flap wheel step can be skipped if your part does not have deep scratches or casting texture.
