The method involves calculating distance of a longitudinal rib (7) in reference to reduction of flow resistance of a body (1) in a medium e.g. gas. A metallic component is formed with negative contours of the longitudinal rib in the calculated distance. The metallic component is formed at or in a film blank by formation of the longitudinal rib. The film blank is provided with a thick layer of 50 micro meter, where the thick layer is coated with lacquer. The film blank is provided with a thermoplastic carrier layer (4) made of polymer or copolymer.
