I have 2010 Infiniti G37S and I'm sure you know that the brake calipers are already have a smooth finish on them. So I'm just wondering if I wanted to paint the calipers on my car what are the proper steps to take?

This place has a wealth of information. Search is a PITA sometimes, but DIY on caliper painting is pretty common thing. Even more so on the 370Z forums.

Shops will charge anywhere from $400 to $1000, depending on lots of factors... on the car, off the car, paint vs. powdercoat, how much you look like you can afford, etc.

Here's an actual tip: look at your rotors first. If the edges and hats are rusting, or the BBK rotor surface is getting worn, you're going to want to start there before you get to painting the calipers, otherwise these pretty calipers are going to be overshadowed by the rotors. Kind of like putting chrome rims on a hooptie.
