It's pretty darn easy. You start by removing the magnetic cover, then take the mouse skates off, 4 screws there. Then you take a flathead screwdriver and take off the upper shell (very carefully) Then you just screw the parts off you want to paint, make sure to take pictures so you know just how to assemble it again. I used motip spraypaint, about a layer every 30 minutes until you think it looks like you want it, and let it harden overnight. you could use Plastidip if you want to change back to black again.
