Hobbies and crafts. I want to paint something plastic to look shiny and metallic blue.?

I want to paint my xbox 360 console a blue metallic candy color.

I know I have to take it apart and I know I have to sand it down with fine grit sand paper.

But do I have to put a layer of primer too if I sand?

And for the blue candy effect..

Do I have to spray a layer of silver paint before the layer of blue paint? Or do I not need the silver layers at all..

If I do need silver first How many even layers of silver should I put before the blue layers?? And how many layers of blue paint will I have to put on top? How many layers of clear coat will i need. At any point after painting will I have to wet sand anything or sand anything before putting on a different layer?

I want my xbox to look like a freshly painted shiny metallic car

What paint brand should I get? What style of paint?

I know I'm gonna need to put a clear coat?

What brand works best...

Thank you very much.
