i have a brava and noticed some rust around the screen and its worse on the a piller should i rub it down and paint it and how can i stop it coming back i noticed my dads marea is the same help please

both cars are fully galvanised so it is very unusual to have rust there. i guess it could be caused by neglect of stonechips. i would clean the area up carefully and then use a rust treatment such as jenolite, and then use touchup paint from the dealer (always a perfect colour match and very cheap)
