Actually not complicated skill, the mouse is very easy to dismantled by removing the 4 screw under the mouse feet, then just rub away the top sticky layer by using sand paper, actually i'm using Dremel rotary tool, after that using fine grade sand paper (i'm using grade 800>1200>2000) to sand it to smooth surface, and then paint spray. The side grip actually stick to the bottom cover, need to use tool (i'm using screw driver) to remove it.
