Well the only thing I don't like when using the PC to remove swirls are, the proper way to remove swirls are to use 15-19 pounds of preasure when removing swirls. How ever when you do that with the PC, the head stops. That only does that so it don't burn the paint. How ever using the PC you can work smaller areas and get better results in the long run. I was told by a pro in 2003, bigger isn't better.

How ever your work is good, you should get painters tape and tape off all the areas that wax could get on. That will stop the wax from discoloring the area. Such as rubber, vinal, etc.

Your doing good, black is never a good color to make look good because it shows everything.
