To use “ultra-Ever Dry super-hydrophobic” water-repellent paint like that, I mean.

People living in Hamburg’s St. Pauli’s nightclub district are used to hordes of drunken tourists, crime and prostitution but many are fed up with late-night revelers who urinate on public and private buildings.

A local interest group has now applied a special water-repellent paint, also used in shipbuilding, on two especially frequented buildings in the renowned nightclub district near the port to deter ‘Wildpinkler’, as Germans call them.

Ultra-Ever Dry super-hydrophobic was developed by auto-makers Nissan. Its oleophobic nano-coating is water repellant, meaning that those revelers who urinate against it will end up soaking themselves.

And here you thought everybody over here was Sitzpinkler.
