Two important factors. Your car is white so swirls aren't that visible, if you have a dark colored car I would'nt recommend that process, siguradong litaw lahat ng swirls diyan pag dark colored car or even a silver car, also Euro car (Benz, BMW, etc) manufacturers use a harder clearcoat than jap cars so it is more swirl resistant. I also had a white car before, swirls are not as visible as on a darker colored car. Swirls are one thing we really want to minimize specially with soft clear coats of jap cars, thats why all the measures and precautions mentioned in the detailing thread. I'm not discounting your experiment, obviously it works for you, just saying that it is not recommended for all.
