stuck hinge

[Don Mathis <donmathis@lucent.com>]

I have a piano type hinge that holds the door to my tool compartment on the
trunk of the Bentley.  It is about 3 feet long.  It won't turn.  It doesn't
look rusted but obviously is.  Any ideas on how to get it loose.  I was
going to make a tank out of PVC pipe and soak it in something.  I'm aware of
the old southern remedy of using Coca-cola.  Any other ideas?  Thanks-
