>>6137227You can do it, but I dunno if a factory could, because I don't know a thing about factory stuff.
But I do have model painting experience. Basically, to do the color yellow over any kind of plastic (or metal), you generally need a white base coat fo primer followed by several thin coats of yellow, slowly building up until it reaches full opacity. Which takes a while, because you need to wait for a coat to fully dry before applying the next.
tl;dr Yellow is a shitty paint to work with.
