processSanding, painting with white, wait for it to dry, sanding, painting again, and wait, just for sanding another time, painting and wait.. if you wonder why require so much repeated process is because we want to eliminate all the printing layers for a smooth surface (the paint act as coating too, so it smooth the layers), you can see a video of a guy making a mini psone that do this same process of multiple sanding and painting here : https://www.youtube.com/watch?v=wbx4bDK9pCE
