So, basically, if chakra that turns to smoke or steam is Futton, then Guy and Lee are Futton users, too.

As far as I remember, the steam released by Guy and Lee is just their vaporized sweat, that's not the same as Naruto.

Anyway, isn't Mei's Boil release simply a vaporized water with a low pH level, I think she mentioned that she could manipulate the pH level of her own technique
