A little radiator lead - what to do?

["Frank Sperling" <sperling@hooked.net>]

I've discovered a little leak in my radiator and am not sure what 
lengths to go to to repair it.  

My '79 B is squirting a little water/steam out of a (smaller than a) 
pin hole near the top of the radiator.

My question is...does this require a radiator overhaul or will some of 
that gooey goopy stuff you add to your radiator fluid to repair small 
holes do the trick?
