Yeah, I'm also curious about how to do the painting. I got some idea of my own but figured I'd check and see how you people would do it!
Based on my research on plastic painting, apparently you need to sand it. I have no idea how you are going to sand the damn thing, with the screw posts etc.
Well, you just get some wet sandpaper, I believe that's what they are called. (You use them with water). You can get those at most autopart stores for like a dollar/euro/whatever.
Obviously there are going to be parts that will be hard to work, like the screw posts, buttons, etc.
My initial idea was to just spray paint the outside of it, but I don't know how that is going to work out with the texture of it all.
Doing it on the inside obviously eliminates that problem but I still have to face the problem of why I'm doing it in the first place, I kinda hate translucent plastic. So I'd still have that translucent, semi-black tint on top of the color I use.
I haven't got mine yet, should arrive this week if the damn customs people get off their butts, then I'd be able to look into it a bit more, but those are my ideas at the moment at least.
