Cali roof leak

[Gunnails]

When I came home today I noticed my Daughters ti windows are all steamed up (the back three), jumped out ready to kick Her boyfriends @ss, but the car was empty and my Girl was inside the house and said she hadn't seen him since the night before, fine, so I forgot about it and grabed my welcome home PBR, and then I got to thinking (dangerous for me) well it has been raining buckets for a few days and I bet the Cali roof is leaking, checked it out and the inside of the roof is dry, but the rear pillars are damp, so now I know we have a leak.
So a couple of questions
1. What is the specific product I should use for treating/sealing the fabrick on the roof.
2. What other areas in regards to the roof should I suspect are the cause of this.
When I bought it a few weeks ago I followed some forum advice and lubed the tracks to help it slide open and close easier ( lithium grease and it helped a lot) at the same time I cleaned the tracks as best I could, even poured water in the track to see if the weep holes were draining, they were, the water runs down a tube and drips out by the rear wheels. Maybe the excess rain overloaded the weep holes, maybe they have become cloged.
When I cleaned the tracks, I noticed some broken pieces in the track that appeared to be the remains of 2 clips that I assume are like positve locking devices for when the roof is closed, roof seem to close tight and seal so I figure I don't need to replace those.
I did a forum search and did not find a good thread on preventive maitanence for the roof, or leaks.

any thoughts any one

I'm not sure but I would still suspect clogged drains.
The water comes out along the chassis rail. It's very hard to see.
There are three (I think) small opening where the water comes out.

found what appears to be the weep hole discharge in the frame rail in front of the rear tire, when I stuck a wire in it, I found it was not connected to any tube, the wire just goes in and you can hear it rattle around inside below the rear window, and the way the top opens up I cant see the weep holes in the track, grrrrrr, I will fix this then let all know how I did it.

yeah ... actually appears to be drains in the 4 corners if the diagram is right. #13 is right next to #7, but you can also see an outlet on the front side closest to you. it also lists qty 4 for the #13 drain tube. i haven't looked at my top and can't power my car on right now to open it (fuel lines not connected). sorry

Therre are 4 drains, the two front are easy to get to, the back ones are harder, but I was able to locate all 4, (1 at each corner) and I stuck a wire down each got it in about 5' in the front and back, then took hot tap water and poured in the track, they all seem to be draining fine now, hopefully chasing down the drains with a wire and the hot water will do the trick, I will repost if I have further problems, any how off to Seattle for the Holiday, Merry xmas all.

If your problem persists, chances are your rubber seal has shrunk at the corners or the seam at center rear. This was actually a recall/service advisory for the '96. The cheap, easy and all together reasonable solution is to get silicone from Home Depot and discreetly squirt it under the seal. Mine had a .5mm - 1mm gap and leaked at the A pillars. $3 and some patience later, it was gone. I should do a writeup in spring. Maybe you can show how to clear the weep holes.
