Zagg “invisibleSHIELD” goes on with water and comes off with water (they say, ". . . it removes easily and doesn't leave any sticky residue."). The shield on my D800 now has some scrapes and gouges, I don't know if the LCD screen would have been damaged. I am not gentle with my gear and sometimes climb in and out of bouncing Zodiacs. The original Nikon plastic cover would be long gone both by detaching and by breaking as did several D300 Nikon shields.
