Great news, this should be widely adopted!

What is AeroSHARK
Rather than being completely smooth, shark skin is unique in its ability to minimize drag through specific grooves, which, in aviation terms, allows for a smoother and more efficient flight.
AeroSHARK replicates this hydrodynamic property on aircraft. It is a "special film" made up of "tiny 50-micrometre riblets that reduce aerodynamic drag during flight."
