Batman has even stated that Superman is beginning to build up a immunity to it. Then again it depends on the writers, because sometimes even a small amount like that has Superman to his knees.
Im gonna have to agree with Whirly here and say Supes labotomizes them both via heat vision.
He also said w/e he has? so he could use the rock kriptonite
