Out of curiosity, where exactly did you blow all the gunk out?

I'm guessing that even if your seal is in bad shape, the water should still be able to be drained through the drain holes, before it gets into the car itself. DSM:reason, I'm having the same problem as you. I suppose my seal is probably in need of replacement as well, but from looking at the structure of the sunroof assembly, even if water was to leak through, it first gets trapped past the tracks and stuff and collects, there, so basically, for it to leak into the headliner, the track area must first fill up and then basically overflow into the headliner, which then would leak onto your seats and stuff.

I know there are drain holes in the rear quarter panels, under the trunk lid. I believe there are some below the tracks of the sunroof also, correct? It looks like the tracks would need to be removed though, in order to get access to those drain holes where the sunroof is located...

Either way, hopefully you get the problem fixed. I'd suggest trying to vacuum out the car and drying it as best as you can asap, to prevent the seats from being ruined. You don't want mildew and mold to start forming inside your seats or underneath your carpet.
