I had a leak in my front hatch last year. Mine was leaking under the frame and not from the gasket. Luckily the core was dry since it was dripping down between the frame and inside trim piece. The PO has removed the frame and put some silicone between the trim piece and coring. An extra 1hr of work he could of sealed the core for good. So I recommend coring out all around the hatch and not just the screw holes with epoxy or resin. I found this dremel cutting tool very helpful.

Looks like the previous owner already sealed the frame screw holes that others have found to be the source of the leak source.
Can anyone point me to/or email me, the pictures of the repair,
