Deck Paint, for interior floor?

[Justin Matesic]

So my units both have hardwood floors, which are in excellent shape (structurally at least). Both have painted floors on the ground level, with the nicer finish upstairs in the bedrooms. 

Without going into a full blown refinishing the floor, is deck paint a good option for the floor inside?
I figure since it will get a lot of traffic, that stuff would be more durable/more protection. Or do they specifically sell hardwood flooring paint?
