I had some rust around my rear fender wheel arches that I thought I could fix myself, until I took off the rocker panel moulding and saw just how bad it was. So I pulled the trigger and brought my car where a professional can work on it.
The guy had mentioned that a lot of rust happened because of the sunroof drain which was clogged that led to the water just pooling on the inside. I tried to find more information on these sunroof drains and where it leads out of but I can't seem to find any. Even the manual don't mention where exactly they are on the vehicle.

Anyway here are some photos.

Seems they have both front and rear drains with most issue coming from the front drains. That's quite a mess!
