1. A method for a protective overcoat for an airfoil, the method comprising:

  • applying a skin (295) to a surface of the wing by wrapping the skin (295) around the surface of the wing from a leading edge (260) of the wing to a trailing edge (270) of the wing; and

    isWherein the skin covers 50% to 70% of a chord length (297) of the airfoil so as to eliminate interference with laminar flow generated from the leading edge (260) of the airfoil;

    wherein the wing is one of a winglet (220,

         230), a raked wing tip and a strake;

    the method further includes manufacturing the skin (295) from at least one polymer; and

    isWherein a trailing edge of the skin is disposed downstream of a point above the airfoil at which airflow in a direction from the leading edge toward the trailing edge splits so as to prevent interference with laminar flow over the airfoil.
