Pencil hardness is the capacity of a given coated surface to resist scratching, marring or gouging by utilizing a value scale that ranges from the softest 6B to the hardest 9H.
How is the test done?
It's a very simple, standard test by going down the pencil grades as you start scratching a coated surface until you come to the first pencil that doesn't scratch the coating.
By using CS-II Titanium Paint Preservation System, you'd actually come away with two layers of actual 9H hardness with a glass-like, transparent texture that will also helps to smooth the unevenness of the surface to provide hydrophobicity.
