Hi, My 2002 Polo 1.2 has signs of rust on the inside of the roof. There are little specks of brown on the felt but I can't feel any damp anywhere. Does anyone know if these could be the first signs of corrosion on the roof? I'm attaching a photo. There is no rust anywhere on the body and it sails thru its mot every year. I want to keep it going as long as I can but unfortunately not able to garage.
Thank you.
Sue
