I'm thinking about PC-7 or JB Weld; those are pretty killer epoxies ... does anyone know ... can I solder it? Weld it? Krazy Glue?

It is a "hairline crack" ... literally the width of a human hair ... and if I squeeze it with my hand it stops leaking.

A auto parts store carries aluminum weld in a tube that's better than JB Weld. And to get a sure seal, sand down the area (coarsely) and follow directions on the tube.

Solder is the only way to go. I wouldn't trust a glue or adhesive, except as a temporary fix in an emergency, and welding will blow a hole clean through the radiator - too much heat! Use a butane torch or acetylene (without oxygen) - the radiator will take the heat away from the area faster than a soldering iron can put the heat it. Get a professional to do it if you can afford it - if you mess up, it may become unrepairable, and new radiators aren't cheap.

If the radiator is brass the best fix would be to solder a brass patch on. If plastic, I'm not sure a good fix is available.
