Unhappy rusting roof panel

Thanks for your note about the rusting phenomenon. Any ideas how this is caused or why it occurs? Could it be the beginnings of rust coming through from under the panel due to the moisture trapped in the sunroof surround? If so, wouldn't it have holes already? This could be a really bad one. What about stonechips left ignored for sometime? The paint layer could have been fractured by very minute cracks which allowed water/moisture to seep into the sheet metal causing surface rusting undermining the surrounding areas as the trapped moisture have nowhere to go. Someone said it could be a bad repaint job or too thick paint used. I thought that Mercs have rustproofing or some kind of zinc plating or rust treatment to all panels considering the prices we pay for these cars. Your ideas will be welcome, thanks.
