It's a thin veneer,so it might be pretty hard to sand back without damaging the veneer.So, to rephrase:
Will I be able to sand down the finish, restain it more blue and refinish it?
I'll most likely take the parts from my RG350DX to make this one, I like more the natural finish. Might have to repaint the headstock though, it's white and all the hardware is black. I'tt look weird with the Quilt maple body!
