A SOFT BARRIER FIN WEATHERSTRIP AND METHOD OF MANUFACTURE ABSTRACT OF THE DISCLOSURE An improved barrier fin weatherstrip is disclosed along with a method of manufacturing the same. The weatherstrip, which is used for sealing openings between fixed and sliding members, comprises a barrier fin preferably formed from polypropylene material, coated or impregnated with wax. The coated fin has good resistance to air and moisture infiltration. The fin reduces the noise generated by the weatherstrip sliding on a mating surface and the breakaway force required to reverse the direction of the fin. The wax in the fin acts as a lubricant between the weatherstrip and the mating surface. The weatherstrip includes a base strip to which the fin is secured and a longitudinally extending row of pile that is attached to the base strip. The weatherstrip can be made by separating the fin from the pile and applying the waxy material to the exposed side surface of the fin, or the waxy material may be applied to the fin before it is secured to the base strip.
