leaky trunk!

so i just got this 4 dr dart sedan. it had a leaky trunk. I replaced the trunk seal and its a pretty good solid fit all around from what I can tell. it did manage to fix most of the water infiltration but i've still got a leaky trunk!!!

I've narrowed it down to the drivers side, but I can't quite figure out where it is coming in. there's no water drips or marks on the bottom of trunk lid.
the only thing i can think of is its running down and behind where the chrome meets the body here? is there a gasket I can stick behind there or should I just tape it off and toss some caulking on it?

any usual suspect leak spots on these things I just don't know about?
short of getting into the trunk and having someone pour water on it while its closed and looking with a flashlight is there any other way to figure out where its leaking?
