Windshield Leak - NOT
Earlier I had my windshield replaced because it was leaking. I think I did an excellent job refinishing the pinch weld with POR-15 and the glass tech did his job installing the glass. However, it still leaked at the upper right hand corner. I noticed that it was not leaking at the pinchweld-adhesive-glass interface, but rather between the two metal sheets of the pinch-weld on video here:

I suspected the seam on the upper right-hand corner of the pinch-weld/A-pillar so ... I taped the surroundings of windshield like below, but when it rained, it still dripped at same location.
I remember that the dripping was worst when I brake or turn a corner, so the idea of water pooling somewhere made sense...
I probed right under the roof sheet metal where water could accumulate around that corner with a tissue paper and found moisture... where the inner sheet metal forms a trough (green arrow) against the outer roof sheet metal...
That strongly points to this worn out seal on the gutter here...
To verify, I covered the whole roof, including the gutters with tarp before it rained again...
RESULT: NO LEAK!
WHAT'S NEXT:
I already have Dynatron 550 seam sealer whose recommended application is either bare metal or primed metal, so I think my next steps would be:
1) Double-check by hosing down that gutter.
2) Thoroughly steel brush everything I can reach on the gutter,
3) Apply the Dynatron 550 by hand, squeezing it well into the crack, let dry,
4) Prime
5) Paint
Your thoughts please, guys?
I wonder why it's not dripping from the door frame pinch-weld which is directly below the gutter.
Do you think the Dupli-Color / store bought spray can primer and paint would be good enough?
