I've searched a few other rust threads but I've not found anything on this area of the car.
Washing my car the other day and found that the paint was flaking off the sills in massive chunks, with some lines around 3 inches long. On further examination the rear of one sill is also covered in rust bubbles under the paint.
I'm going to get a rust treatment and re-spray done on the area (or new sills if they're completely gone underneath) but has anyone came across this before? Can the sills retain water from inoperational drains or anything like that? Just so as it doesn't happen again.
