The present invention relates to a manufacturing method of an automobile weather strip. The automobile weather strip includes: a seal unit of which the cross section has a U shape and which has a sealing function; a combination member which is integrated with the seal unit and is combined with the flange unit of an automobile; and a core which is inserted into the combination member. The manufacturing method includes: a weather strip forming step (a) of forming a weather strip by extruding the core and thermoplastic elastomer; a primer applying step (b) of applying a primer onto the surface of the formed weather strip; a slip additive applying step (c) of applying a slip additive in which silicon and polyurethane are mixed onto the surface of the primer applied in the primer applying step; and a hardening step (d) of hardening the coating composed of the primer and the slip additive. The automobile weather strip manufactured by the manufacturing method described above can improve the emotional quality, stiffness, and wear resistance.
