Sorry to start a new thread on this, I couldn't retrieve the old one.

Final chapter in the continuing saga today.
Mineral spirits didn't touch the goo.
Here's what did:
Smeared the residue with stuff from an ancient bottle of Turtle Wax Bug, Tar, & Tree Sap Remover. (an ancestor of Goo-Gone?) Let it sit a few minutes. Rub until some of it moves around.
Soak a rag with lots of kerosene (lamp oil). Wipe the goo away. Repeat the drill if some of it won't come up.
