Sounds like it’s time to grit your teeth and replace the radiator. I would bet your threads are boogered up. Brass or aluminum is soft. It’s easy to torque through them by hand. I know from expience, not to mention cross threading. I’ve killed soft metal threads with a tap too. Honestly, I seem to remember my drain plug having a stop. I know I’ve never completely unscrewed it.
If you’re really bent on keeping the wounded radiator, I would remove it to dry that damaged area and I would JBweld it. I have done that on a Griffin radiator transmission cooler fitting.
Personally, I would swap the radiator.
It doesn't matter who you are until you are whom you are supposed to be.
