Hi Curtis. I care my Black 330Ci so I know what you'll be going through.
I do recommend getting a PC. It makes taking care of swirls and light scratches much easier and faster.
There are three products that I definitly recommend. Use Poorboy's SSR1 with a polishing pad for light spider webbing and swirls every two months. On my wife's silver TT, I only have to do that once a year. Welcome to black cars. The second product is either Clearkote's Vanilla Moose or Poorboy's Polish with Carnauba with a polishing or finishing pad. These products will give your car a great deep, wet look that is perfect for black. After polishing and glazing, you would need a final topper. Some here refer to it as an LSP. The choice is yours of wether or not to use a Caruauba wax or a sealant. My favorite waxes and sealants are Poorboys EX-P, EX, Natty Wax, Pinnacle Souveran, P21S Carnauba Wax, and Wolfgang Sealant.
All of the products that I've listed are much easier to use than the one's you have, and I personally think will give you a better look.
Get some nice microfiber towels for buffing residues and use very light pressure careful not to induce micromarring.
GOOD LUCK!!! It's not easy keeping a black daily driver in perfect condition. The beauty of black, though, is that you are greatly rewarded for doing so!
I hope I helped and have fun!
