Yup, many times including a week ago when my rad started leaking 25
miles from the nearest house while i=on vacation.  It stopped the leak
at the end of a core and made it back a couple hundred miles home.

I am going to remove the rad before winter and solder up the leaky core,
but 'really' didn't want to have to do it on my camping vacation. (I
carry the tools)
