I have been thinking of a third method to seal this leak:
After you have cleaned around the leak and made sure that the leak comes from a pinhole, drill a small hole right in the centre of the pinhole, tap a 3/16" thread, buy a 3/16"" brass screw, apply some Loctite to the screw before screwing it in place.
