Next dilemma: 1967 R60/2. The fuel tank has the tiniest leak. So far I have not found the exact location. I've mounted the tank, full of fuel, an inch above a flat table with clean cardboard under the tank. Over night I get a spot of fuel under the left front of the tank. I'm guessing the seam is leaking but not sure yet. I will continue to investigate.

So what are my options? I've heard of fuel tank coating but will that cure a leak. Thanks for a little guidance.
