It is not uncommon to feel a bit frustrated when first starting out. First, never let any paint whip you. You have to show it who is the boss. Who is the boss? Jim! Like MJ said, some water spots can be difficult to remove, especially since they may have etched the clear coat.
You may want to start with a small 2x2 section. Let's get that small area perfected before we move on. Your pads and products are good. LC orange with the WG Total Swirl Remover can tackle some nasty defects. Downward pressure on the PC is important. Take a Sharpie marker and put a thick line on the outside edge of the backing plate. You want enough pressure on the pad but still need the pad to rotate. The mark will let you know if the pad is spinning properly. Move slowly with your passes like in the video. It may take a few section passes before you see the results you want.
Take your time and work small. Move down from the orange to the white pads if you have some. Finishing Glaze on white should finish down great without needing the black pad. The black has almost no cut at all. Nissan paint is fairly soft so the orange and white should get it done. Deeper defects,scratches will not be removed with the PC but don't worry about that. We all strive for perfection and have to live with some imperfections.
