FP - I did mine myself on the car. Jacked it up, pulled the tires, cleaned it, taped it off, scrubbed the back to the wheels to get them clean, put the tire back on ..... rinse & repeat 3 times.
I think it took me about 1.5 hrs to do the whole car. I got caliper paint at the local auto parts store. They had lots of colors, but what other choice did I really have but red on a yellow car??
If I can do it .... you can do it!!
