What can I say! THANKS, THANKS!!! This thread should be pinned!
This solved my raining problem inside, it was a total nightmare, water was leaking everywhere, had soggy a-pillars, roof light dripping over the ICS and seats, BIG puddles building on the floor (water would reach my ankles!)
I had removed the whole sunroof, found no cracks or leaks, sprinkling water over the car didn't reveal any leak, it was something strange that would only happen after hours of raining.
Of course after the job of removing and fitting everything back, next day it was wet everywhere again!
As described, I gave some silicone with the finger all over the edge, it's beem two weeks with heavy rain, no single water drop has entered in since then.
Wet socks smell gone, nothing wet, no more extreme condensation building on the windows... At last!!
