Default Expansion tank leak - pin hole

I have had a small leak after installing a 60's style expansion tank and I think I have found where it orginates. It does not leak when cool but when the engine warms up and makes pressure it creates a very small drip on the bottom of the exp. tank that will leak a couple of drops per drive directly on the top of the alternator. The leak is not located near any hoses so I think I have a pinhole in the exp. tank. Do I need to take the tank to an radiator shop to have it repaired or is there a product (JB Weld?) that one can use to alleviate this problem.
Thanks for any assistance!!
