Oh, do you mean the spot? I commented about that, It's the paint, coloring the switch was my very first experience with spray paints, and that brown spot is a dust particle and i didn't want to add another coat of paint because I was afraid to ruin it.
I plan to order another housing to fix my mistakes though.
No I meant by the bezel next to the Y button.
I didn't know you painted it yourself though, that's pretty cool. Most people just buy replacement shells.
But you still need to get white sticks, D-Pad and shoulder buttons/eject button if you want it to be fully white. Did you paint the rails white too?
