Getting his with can would ruin your whole afternoon. One ship in the Pacific had a pump and hose to shoot a combination of gasoline, diesel and detergent. They would cover the attacking boat with it, then aim Roman Candles at them.

they typically use water cannons , loudspeaker blasts and lots of lights...not much protection there.
