Before anything happens you must first take apart the controller, if this concept scares you, turn back now. I found that the people at Llamma.com
have detailed instructions for both the disassembly and assembly for the wired and wireless controllers.
Once the controllers are disassembled, we will need to sand down the gloss on some of the surfaces of the controller. Since the Xbox controller has few of these this is a simple step. The parts that I had to sand down were: the RT and LT, RB and RT, D-Pad, Start and Select buttons, and parts of the battery. The sanding on these parts should be minimal and just enough to take off the shine of these pieces. Before you start painting read the instructions on the spray paint as some of the different types of paint suggest steps for better paint application. My paint suggested I rub it down with some paint thinner to get rid of loose particles and debris. Don't forget to shake the spray paint for 2 or 3 minutes.
