If you have have the time to spare, I'd recommend re-painting the vocoder though. I've re-done mine 3 times, so I know it's tricky.
The best way to do it is to sand down your existing paint, with a pencil draw outlines where you want it to be, and use a flat round-tipped brush (also known as a Filbert brush) for the paint, starting at the top of the vocoder, doing the strokes downwards.
