Okay, here's a couple of pics of the Gold Strat body I took just after I finished spraying it with White Knight White Undercoat paint, I checked to see if there were any major issues but it looks fine apart from some paint runs, it was already touch-dry when I checked it a minute ago:
I reckon all it'll probably need is a light sanding to even out the surface and then a second coat of Undercoat and then I'll be ready to spray the body with the Gold paint.
