Thanks for the reply. To be clear, there really isn't anything going on on the surface of the roof - this spot under the glass is isolated there. It's kind of weird. If it matters, I have a moon roof and the moon roof seems not to have any issues either.

My 2010 Fusion has a small rust area under the top edge of the windsheild. Narrow, about 1.5" side to side extending about .5" under the glass. Any way to mitigate this that's less intrusive than removing and remounting the windsheild?

Looks like it may have worked! - there's been some rain, nothing in the well. I do have a moonroof - I guess it's the right rear drain?

I have had persistent water in the right side trunk well (jack storage area.) Yesterday I reached into the cavity between the inner and outer fenders (where you can see the backs of the marker lights) and found a hose that was SUPPOSED TO drain to the exterior but was flopping around loose. I poked its L-shaped connector back into the hole it was meant to go in, and I'm planning on securing it there with a bit of duct tape, since the snap connector got loose somehow. Is this the A/C drain hose mentioned elsewhere? That drains into the front foorwells when it's clogged - I guess that's different. What's the hose I found? I really hope that move fixed my wet trunk problem! New here, first post, thanks for the help.
