Thanks guys, I have two of the plastic SF kits myself. The logo you are correct about, all you see at the moment is the alpha for the logo, I haven't painted it on the colour map (I forgot actually and realised the other day too!).
As for the paintedness of them, well I don't know, I kind of follow the theory and principles of fighter jets, where they are painted grey or what have you (I assume?!), and there for make the claim that SF's would also be painted for some kind of protective purpose. Dunno for sure though heh.
Cheers!
