Hey, that's looking good H, even though the photographic studio is a little bit strange! It'll be ok now, but for future reference when doing bare metal finishes, paint the solid colours first, then mask. Solid in this case being the black and white stripes, and the blue. It's easier to paint them, let them thoroughly dry, and then mask the relatively smaller ares, than the other way around. It also prevents any 'silver' creeping onto the areas where solid colours will go, which can re-act and show through. Good job mate.
