needsome advice on doing a TF repaint

Posted in Custom Workstation

I just got a Transformers Human alliance Skids, and he looks good, but me being a car customizer I want to spray him with the similar green and a heavy clear coat like a real car and make him look "real".... I see all the obvious screws holding things together but all the joints have mettle pins that I don't think come out (unless they do, then please share how), so how would I spray him without the joints getting stiff and no longer working?
