"Pinhole" radiator leaks are not rare. Like with gas tanks, they usually forecast big problems because the metal is thinning due to erosion. Vibration over the years can cause the fins to pull away from the tubes, leaving weak spots, often deep in the core where it can't be seen. Any Barr's is effective, but usually not a permanent "fix". Glycol based antifreeze has a very low surface tension, leaking where plain water doesn't. Only radiator replacement is the permanent cure, and offers increased cooling as a bonus.

I recommend getting the radiator fixed.

I'd strongly recommend the aluminum powder. Use it per the directions. You'll be pleased.

I know everyone recommends Barr's, but which one. There is the aluminum, pellets and so on. It is for a 36 ford car. A very small leak in the radiator that I can not even find but see a small amout of fluid on it underneath. And it is not the hoses.
