Trunk full of water-rear seal pt II

[samiam4]

I've got a W123. I purchased a new seal(trying to fix a trunk full of water). New seal leaks badly too=0). There was some greyish material around the bottom of the rear window opening. I think it's a tail tail sign that the factory installation used something similar to 3M "strip caulk".

I spend an hour last night digging around in W123.130 EPC and found this "$1.2 /meter A001 987 56 46 Sealing cord, Paint run off hole in Rear window opening".
It was in a stray area of electrical- so I have no idea if this will help or is where it's installed. I've done them before- and of course it's my car that leaks. I could do this or just let the glass guy goo it in place.
