Why? Because it's not tracking greasy $hit all over your track. If you showed up at a "real" race with something on your tires (or anywhere else on or around your car) that got onto the track you'd be shown the door in a hurry.

And using Niftech is such a pleasant experience compared to the others (ESPECIALLY Jack the Slimer)...daub it on, let the carrier evaporate off. No greasy, oily, nasty gooey tires to deal with, wipe, rub on your belly (yes, I've seen your shirts...) OR GET ALL OVER THE TRACK.
