water leakage

 Last week or so I noticed some waterdrops via the front ceilinglight. And it happened again, so I was wondering where it was coming from. I thought it was maybe via the antenna as they did mounted one at the front middle. So perhaps water was going via the antenna cable just above the ceiling light? All looked good on the top

And underneath as well, no signs of water:

On closer inspection on the window rubber seal I spotted these corrossion spots:

And this must have been causing miminal leakage underneath the rubber somehow, which was evident on the inside of the roof edge, a few small rust spots and water found it's way into the ceiling light.

Since the car was parked in the garage the last couple of years this now manifest with the rainy weather season and being parked outside on the street. It is minimal though but time to tackle this. Next I found two small issue's at the rearside doorwindows where a little bit of rubber trim is missing in the pilar on both sides:

First I had everything sprayed with rust converter and primer:

Next I had put black kit on it for final protection, including under the top window rubber. Not the cleanest job but sufficient for now. 

While scraping off a little excess of spray and kit some small paints chips manifested, so that needs to be resprayed next time.

It was rainy last night and today and so far it looks ok though. I think I will drive it through the car wash so I can have a better look. In fact I just did that and it looks dry:

And after another rainy night I had it inspected this morning and all is still dry. Good.

I also wonder what all these connectors (3 seperate cables with connectors) are used for, which are coming out of the ceiling, I can only identify one which can be fitted into a module (which is not present in the ceiling headlight). I think that one is for the remote control (which is not working - another item on my todo list).
