I know these cars are common to leak. One that'* been pissing me off and baffling me since I 've owned the car is the rear left part of the trunk in the corner by the tail light.

Sometimes after the rain, the insulation is soaked, sometimes its completely dry.

Could this have to do with the fact that the top stud on the tail light is snapped and needs epoxied?

What are some other things I can do to fight this leak? It doesn't really create puddles, but it SATURATES the insulation.

Yes. Those studs provide the clamping force to make the seal between the lens and the body. Remove the lens from the car, make sure you have a good seal, repair the stud, then pull the lens up evenly but not too tightly with the nuts on the studs. I use 3M strip caulk to re-seal when I can, because it allows disassembly when necessary, but seals very well.

Pay close attention to the body seams around that light also. I had to re-seal them on one side. It was weeping in there.

I've taken on the habit of drilling small holes in the underside of the connector cavity on my tails to allow water to drain out before it can enter the light. I also use the 3M body and trim sealant (black) around the top half of the tail rubber seal like an 'eyebrow' to add another safety.
