The most likely cause of rust around that area is due to the screen being replaced in the past and them being a bit careless with the bonding removal tool and damaging the paint work.
The rubber trim around the screen actual does very little sealing at all.....
Good point Mark.....I watched as blokey at Autoscreens did mine....I thought at the time I hope your being careful with that cutting tool getting old glue off.
He told me that 38% of the strength of that area is due to the windscreen......and they go glue it in!

Also he reckoned mine is on at least its 3rd screen.....apparently my old one came out too easily for it to be original.
Oh and summat else I remember....i think Ron said when he had a new windscreen.....he had to go out and buy external Ariel for his sat nav.....coz blokey told him you to have heat reflective screens fitted now....these type have silver in them and block the satellite signals. This isnt the case coz i had an ordinary screen put in mine. Autoglass bloke said i can either type fitted.
