COAT is a Yin-Yang release jutsu that requires Six Paths Senjutsu. It seems that the Six Paths Senjutsu gives the user the ability to use Yin-Yang release effectively. Naruto has a fraction of Hagoromo's Six Paths Senjutsu, so if anyone has the potential to use something resembling COAT, then it's Narujesus. Although why he wasn't able to restore Guy's foot, his own right arm and Sasuke's left arm is beyond me. This is why I'm still confused if Naruto can still use Six Paths Senjutsu by the time of the Boruto movie. Maybe he lost the power after sealing Kaguya, which seems unlikely since Sasuke retained his Rinnegan.
