Scirocco Central

Right where the roof meets the top of the windscreen, as per attached pictures. It's gone right to bare metal. I have NO idea how or when it happened, but there is it.

Does anyone know the best way of correcting this? I have the touch up pen, but would this be a job for spray paint... or body shop?

Tart it up with the touch up pen. Painting a whole panel usually cost the same as a little spot. Then when you got more to paint you get them all done.
