"Relining" usually refers to a chemical coating that is applied to the
inside of the tank.  JC Whipme sells this stuff but I have heard mixed
results with their brand.  One of the more highly regarded products is
available from Bill Hirsch Auto at

This product is popular with the antique truck crowd.

So what's "re-lining" a gas tank? Who does it? What does it cost? etc. I
have doubts about my own gas tank ---- and I thought the only option was a
new one.
