Windscreen Seal / Bond Issue On 59 Plate Fiesta

[coysht]

Evening all,

I've got a 59 plate Fiesta Zetec S and while cleaning it at the weekend I noticed something odd going on with top of the passenger side of the windscreen (see attached image).

To me it looks like the screen is coming unstuck from the sealing bond (either the bond from the screen or the black masking paint coming away from the glass) - which if it gets worse will cause it to leak!

Anyone seen anything like this before and/or know how to get it fixed?

If my suspicions are correct, I'm guessing it's a screen out and back in job or even a whole new screen - which I can't see being covered by my insurance's screen cover.
