Spray paint 5700XT (thermals question)

Hey, I’m planning to spray paint my girlfriends 5700XT. I was wondering if anyone had done this before and could give me some tips and guidance? I only wanna paint the plastic around the fans, and possibly the fans. I know I have to be careful painting the fans because of imbalance if I were to not spray properly. What I wanna know is what sort of spray paint do I need? Do I need a specific one or does it not matter since I’m not spraying on any of the thermal conductive parts? Thanks in advance.
