Alright, so I got my screwdriver and opened up my GCN controller. Then I painted the outside of it with three coats of gloss white Krylon plastic paint. It turned out really nice, and so I put my controller back together. Then I noticed the horrible purple color showing through between the crack that separates the two pieces of plastic.
Bleh, so I just reopened my controller and painted the back. Now I'm waiting for it to dry.
Although I think it's dry now. So I'm going to put a very light fourth coat on the front and back. I accidentally scratched them with my screwdriver from the excitement of wanting to see the controller all fully assembled.
My tip: Paint the front, let it dry, turn the pieces over, and paint the sides. Yay! >_>
EDIT: Ok, I finished it! ... well, kind of. It's done if I don't want to put any logos on it. I want to put something above the start button, but I don't want to mess up and screw the everything up.
I bought a silver and a light blue paint pen (Yay! Wii!) And I'm thinking about either putting an Armored Frog silhouette or a a bass clef. The bass clef would be the easiest I would think. But I'm not sure how to start. Any tips or suggestions on putting an emblem/logo above the start button? It doesn't have to use my paint pens idea.
