Yes the lens is leaking. I ought to try taking it apart and rebedding it. Not sure there's a downside since I'll have to get it professionally done anyway, if I do nothing or if I screw it up.
Either way, I REALLY want to stop the leaks.
Rebedding a lens is an easy task, the real work is completely removing all traces of the old sealant from the lens and frame. If the lens is vey hazy you might replace it now. You make a nice thick bead of silicone sealant in the frame, then seat the lens into the sealant, adding more from the top as needed. if you tape the lens edges, where it meets the frame underneath, and on top, you wont have a problem cleaning up the cured sealant, which you do with a razor. You need to treat the lens and I believe the frame with a corrosive primer to give the silicone a finish to bite on. I'd contact your hatch manufacturer for thier product recommendations, you will sell you thier sealant and primer for 3 times the price of similar stuff.
