Ah, okay then.

Though I should point out that, in the anime, Luffy always uses Gear Second on his entire body. From how the anime depicts it, the only thing Luffy upgraded on his Gear Second is that he can do it in any position he wants.

How the anime depicts it is how I believe it's working out even in the manga. We just never quite see Luffy in a good position to see that.

Except on one part...

And it doesn't look like steam coming from the fire either.

Sorry, but I simply see no evidence that in any media, rather it be manga or anime, that Luffy possesses the ability to focus his Gear Second form to any individual part of his body.
