cracked oil pan

I seem to have a tiny pinhole or crack in my oil pan, leaving a tiny puddle of oil everywhere I park. At first I thought the leak was the result of the drain plug not being tight enough, but I've tightened it quite a bit. And I've noticed that where the oil droplets are appearing, just under the drain plug, the oil pan has been scuffed. I wipe away the oil droplet, and (when the oil's hot) a new droplet forms within seconds. I do not see any movement of oil from the drain plug to the scuffmark, so either the oil stream (at most a quarter of an inch long) from the drain plug to the scuffmark is so thin as to be invisible, or there is a tiny hole in the scuffmark. I think the latter is the most likely.

Is there a way to repair this leak that does not involve removing or replacing the oil pan? I was wondering if I could fix it by applying some epoxy or gorilla glue or something else (suggestions?). I figure I would have to wait until the next cold morning so the oil is very viscous, clean all the oil off the pan with solvent (alcohol?), and apply the glue. The glue would have to dry before any more oil drips out.

Alternatively, if anyone has an old oil pan they don't need, I'll happily pay for shipping and a token amount for your troubles, but I'm on a low budget right now.

Thanks for any help you can offer.

Just buy a new oil pan -- it's just a little nickel-dimer. We get $27 for it.

Bad news is, that nothing will stick to the pan with oil in it.
Good news is, that those pans are easy to remove and can be wire-welded or brazed without a problem.
I would more worry how the holes started. Do you have a marks of the pan rubbing the road? Maybe corrosion?
When you have corrosion with dripping holes, there is not much left to repair.
