Hey Andy,
I don't want to burst your bubble but i do believe that the center section of the wing on the real one has actually been painted with an aluminum paint to keep down the corrosion level. As this is the main walking area on the wing.
No bursting of bubbles at all. You are correct. I had to verify it with the maint. company who worked on the jet. That portion of the wing was painted no so much due to that being a walking area but because it was a different type of metal that wouldn't polish out to match the leading edge and trailing edges. Also the whole bottom of the wing and the tanks were painted. My model will be painted in these areas to reflect the scale bird.
