GE bottom freezer gbs22hbsww 3 years old

My refrigerator leaked a thick, brown, sticky, and oily substance at the seam behind
the bottom freezer door, lower left corner next to the door hinge. It is very small leak. It is odorless. The substance is sticking to the gasket, and it can't be cleaned off. What is it?

could be permatex gasket cement.
