Sure nuff, the puddle of water reappeared. But from where was the million dollar question.
What I noticed was a trickle of water running down from the inside of the trunk just above the left tail light. When I checked the outside, there was really nothing overtly noticible. But when I checked the trickle of water (during the rain with my trusty umbrella in hand) it seemed to be coming from NOWHERE. Upon futher inspection, there was a channel of water that would drain from the rear windscreen into a pathway behind the trunk edge, then down the left side of the trunk edge and then down to the right side of the left tail light. Here's the kicker - there was an unwelded seam just above the tail light through which water was entering, hence the souce for the trickle of water inside the trunk. - Water (I mean 'what a') kicker.
I shined a light on the inside, and again quite unnoticible, the corner was not covered with tan sealant and also one could see the light glow from the outside.
The corresponding seam on the right side of the trunk was welded.
So I did the next best thing to welding. Out came the caulk gun and the elusive hole was sealed. I must say that this is an extremely unusual location for a hole through which water can enter the trunk during a rainfall. So alas, let us await the next predicted April shower for some success and an end to the bewilderment of this leaky situation. :)
