I tried it out on the hood of the Aurora today. On one side I used #80 and an 8006. On the other side I tried ZPC Fusion and an 8006.
One thing I noticed was that the paint never got remotely hot. It only got slightly warm (the garage was about 55F). I started out at about 1200 rpm, but that seemed absurdly slow, so I turned it up to about 1400 rpm.
Even that seemed pretty slow. I've used a rotary somewhat in the past, but not a lot. I had only used a DeWalt, and it seemed a lot more, I dunno, worked? at 1400 rpm. It was loud and blowing air and whatnot. The Hitachi seemed like it was barely doing anything. Maybe it's the smaller pad size? Is that what is responsible for the lack of heat too?
I moved the buffer slowly around, like a little less than an inch a second. But I didn't feel comfortable moving it more slowly than that.
Both the #80 and ZPC brought out even more of a gloss than was on the car. It was kind of neat since it was already in nice shape. When I see talented people use the rotary, I think it can actually make a nicer gloss than is possible with an orbital tool. It's not a matter of stepping down and taking longer with the PC, I think it just can't reach quite the same final finish, though it gets quite good. The ZPC minimized the random scratches better, but neither removed anything, not that I expected them to on the speed and pad I was using.
I barely splattered anything, I was nice and clean at the end. The ZPC splattered a bit at first as I guess I put down too much, and it's more runny.
Oh, one thing I kind of noticed was that to keep the rotary from pulling me around, it helped to slightly torque it opposite the direction of motion, i.e. apply torque such that it would lift the forward edge as the buffer is moving, but not enough to actually lift the pad. Is that an acceptable practice? It seems like when the pad is truly flat, the buffer wants to get pulled around by the pad, mostly in the direction of rotation.

don't know if the instructions have it.
