My vote is for JB Weld. It's good stuff. However, my first thought would
be to replace the entire pipe; ie, if it has some pinholes now, it will
have more soon. If the pipe's so thin that it is leaking through the wall
then it's probably worn out :-)
FWIW, I have not had many great experiences involving solder and coolant;
it was either a botched soldering job (likely) or the coolant melted the
lead.
Also, the JB weld is thicker than lead can ever be, it shouldn't be able
to seep inside the pipe. Let it set up for a few minutes before applying
it.
