We saw your discussion with Rasky on the other thread and feel the need to point something out:
Infiniti's underhood stickers referencing "Hard Clear" and "Special Repair Procedures" are really only applicable to their paint systems relative to each other. Rasky has tons of experience polishing all kinds of paint, so when he says a paint is hard, soft, delicate, middle of the road, etc we're inclined to take his word for it, no questions asked. But keep in mind that his experience is on the cars he has personally worked on, not on your specific car. His specific works were "I'd say it was on the harder side, but not like some of the German cars I've worked on. It required D300 to be worked with heavy pressure, slow arm movement, and smaller section sizes."
There's a definite difference between "on the harder side" and "hard like some German paints" and, quite frankly, we'd be surprised to find that you car had truly hard paint, as most people would define it. And given the progress you've made using just light pressure, that just reinforces that notion for us. With the DAMF System you are almost always going to use at least moderate, if not heavy, pressure (except for the finishing wax step, which uses just light to moderate pressure and fast arm speed).
Now, from that other discussion it appears you're using a Flex 3401 here and not a traditional DA (G110v2, Porter Cable, Griot's, etc), correct? If so, you're best bet is to use that tool at speed 3.5 (give or take a bit) and moderate to heavy pressure with slow arm speed across the paint. But something important to keep in mind here; the potential for hazing the paint is greater when using a forced rotation tool like the Flex than when using a more traditional DA. That means odds are you're going to need to follow up D300/DMC6 with M205 on a finishing pad at slower speed and less pressure to really maximize the finish. This system was really fine tuned for use on a traditional DA but can definitely be used on the Flex, just with that knowledge in mind that it might haze a bit more. And the more delicate the paint, the greater the potential for haze, too. And sometimes Japanese paint can be a bit on the delicate side, even if it is a bit resistant to correction. But again, that's a very broad generalization and may not relate to your paint at all. Only you can tell us that.
Nonetheless, using light pressure alone isn't going to cut it for you (no pun intended). Don't go crazy on the pressure, but definitely increase over what you've done (and fairly significantly) while moving slowly and working small areas. You'll get it.
