The radiator is easy to replace. The hardest part is removing the fan, which has some rubber grommets that can be a pain to get off. Silicone spray helps a great deal.
The jbweld solution is actually a pretty good idea. The leak is so small that this is a great application of it, especially in a pinch.

Its the perfect spot to spring a leak. A tight radius corner on the inside of a piece of plastic thats attached to a lever (hose) connected to a vibrating and rocking motor. If the radiator was going to crack, thats
exactly where I would expect it to let go.
You can JB weld it in a pinch, but once the crack starts in the radiator tank, its going to keep going. The JB weld is really just sealing the leak. Sooner or later, you're going to still need a new radiator. Probably best to do it before the whole hose neck lets go. Upper radiator necks seem to be a BMW Achilles heel. I recall this being an issue at least back to e36s.
