Water Leaks Into Trunk Strange Rubber Goop Help!!!

Hey folks, so for starters I bought this car off a guy on craigslist approximately a year ago. Recently I've been noticing water getting into the trunk from rain. Now I NEVER noticed this but as I looked to inspect trunk I noticed wild looking black goop all over the place. Now I figure I was hoodwinked but now I am desparate as to what to do to resolve this and if this stuff the previous owner put on inside the car is worth doing again to seal it.

1. What is this goop??!?!?

2. Where can I go to get this fixed?

3. How much am I looking at roughly?

Keep in mind this is what I just saw inside the trunk. Any help would be greatly appreciated in identifying what it is and what I should do as a temporary/ permanent fix.

Thanks!

It looks like seam sealer, it fills the gaps between the panels on the floor to keep the exhaust and water out.
..and it looks like someone tried to seal up the back window with it. If it's the window were the water is getting in, then the window will need to come out and the window channel repaired.

I'm guessing that is where the water is coming in as well. The question becomes now... who would be able to repair such and at what cost approx?

Any general bodyshop?

This is what the driver-side rear window area looks like.

looks like you are past the point of only just the window channel being replaced. With that much sealer, the package tray support is probably rusted or gone completely. Look at the other side in the same place and see if there is any evidence of water \ rust there. Maybe it is just the one side. Does the metal package tray support look as all good metal where it attaches to the side of the car? i had to cut up another car to get a complete package tray support to repair mine. both sides were no longer metal attached to the sides of the car. mucho dollars.

Water is laying in the areabetween the molding and the (shot) vinyl top. This probably caused rust-out in the corners. The trunk (where the black alien egg case is) then begins to leak....this usually results in trunk floor rust, and possibly rear seat/package tray area rust.....must be fixed from the outside.

That was my first thought when I saw the photos too. My 69 had the same problem on one side. I guess it's a design flaw. Water can't drain from the corners of the rear glass so it just sits there and eventually rusts. In my case it got not only the window channel on one side, but also the bottom edge of the quarter panel behind the wheel and part of the wheel arch too. I wound up replacing the whole quarter, patching part of the wheel house, and patching about 6" of the filler panel that extended from the edge of the quarter towards the center of the car. Did it all myself. Sure was a ton o' work.

I started to grind out the lower window channel because it was full of bondo. I found chunks of crumpled up newspaper, chunks of wire mess, tons and tons of bondo. By the time I finished grinding out the bondo the filler panel almost fell out on it's own!!
