Taking the brake calibers apart is decently easy. If you have basic hand tools, than that's all you really need. As well as a C-clamp to seat in the brake pistons back a little. Other than that, you should be fine with the video guide linked above.
I've personally used Duplicolor Brake Paint
in the past with a few of my cars. It seems work nicely and stay clean over time. I suggest taking a look at some of our customer submitted photos for real life examples!
