Anyone have a suggestion of how to repair a pin hole in my oil pan, without removing the pan?

The motor is running fine. Rebuilt 350 HO, 18 heads, all original. Has the BOP remain seal in it, motor not leaking anywhere. I checked under the car today after taking it around the block, and saw a puddle. It looked like it was coming from the oil drain plug, but a small pin hole next to the oil drain plug.

Thanks for all the advice from everyone. I look forward to passing some of the tips on.
