The misconception with many people, and what gets them frustrated, is that the mere fact of applying product on the car doesn't automatically mean they're going to get results.
"clay,1zpp,1zmp,1zgw, waiting on the gw to cure so I can apply pinacle souveran."
I think it would extremely difficult to effectively do 4 different steps in 1 day properly without a PC/Cyclo. You would just begin to get tired, and end up rushing due to the amount of time spent.
You have to know, and think about what each step is supposed to accomplish. Not just apply one after another then expect results.
Clay should remove the bumps you feel when you put your hand over the paint. A cleaner should remove oxidation, water spots, etc. A compound should take coarser scratches and turn them into a haze, or much lighter scratches. A polish will take this haze or lighter scratches and mill them down further. Once the paint is smooth, clean and swirl free, then you apply your protectant to preserve your work. So after each step, if you have not accomplished what the product is supposed to do, continue with that same product, do not move on to the next step.
