I've got perennial water leaks into the trunk of my 86 Saab. Of the several sources, this 1/8th-inch vertical seam gap at the rear taillight area is the biggest:
Small-handed Swedish trolls originally stuffed some hard black cr@p in there; it cracked and crumbled when I prodded it.
What product should I replace it with that will last another 20 years? I'm happy to pay for the best stuff -- it need not be grassroots-priced; it only has to work really well (I'm tired of a stinky, moldy car!).
id use a little piece of aluminum flashing and construction adhesive.
edit: use the construction adhesive to be the "meat" in an aluminum sandwich; aluminum folded in half and over both inside and outside surfaces whiles bridging the gap.
the 100% silicon would work well too.

Silicone works fine. If you put some masking tape behind it, you can get a nice thick bead.
3M strip caulk. It has the consistency of modeling clay and it never hardens. Here's what it looks like, but you should be able to find it at a decent local auto parts store. http://www.tcpglobal.com/AutoBodyDepot/ItemDetail.aspx?ItemNo=MMM+8578
It's called seam sealer. Autozone carries it by their body supplies. Comes in a caulk like cartridge. Eastwood and any good body shop supply store will also carry it. You can get it in black or grey depending on the manufacturer.
Shoe goo. Stays fexible. Make a little dam with tape that holds it in place til it sets.
