Silicon is readily available and dries quick and works. Over a short period of time it yellows and looks yukky. It also leaves difficult to remove residue on the skin.
Vulkem needs to be ordered, dries a lot slower, and also works. It more closely matches aluminum color and is what is used at the factory so it is less likely to look like a repair.
You could also try using a pressure washer to try and figure out where the leak is coming from. As you mentioned, leaks travel and where it comes out may or may not be near the source.
