Windshield Leak?

[jstatic77]

Hey I'm Joe,
I picked up a 75 C10 a while back. I believe the windshield is leaking, my seal appears to be good, i found just the upper corners from rubber seal to cab to have caulk, but curious if the seal should be set into a bead of caulk all the way around especially at top & side of cab? then install windshield.

Check your cowl under your wipers.  Most leaks are from rust holes down in that area

Found it..... after a water test, the upper windshield gasket took in water and went to drain hole that has rusted out and leaked to interior. I flooded the cowl and nothing, flooded the lower windshield and nothing, then the upper and what do you know, it leaked.
I feel a weld repair vs. bondo is the way to go? What do you think? Should I keep hopes or fill in? Photo of bad side andphoto of good side
