Include me among the 75 percent of people who touch the surface next to a Wet Paint sign. This sign, obviously being a close relative of the Wet Paint sign, had the same effect. My hand automatically reached out, index finger leading the way, to see what was going on. Unlike most Wet Paint signs, this was accurate.
