1. A vehicular slider window assembly, said vehicular slider window assembly comprising:
at least one fixed window panel, said at least one fixed window panel defining an opening;
an upper rail and a lower rail fixedly disposed at said at least one fixed window panel;
a movable window panel that is movable along said upper rail and said lower rail, wherein said movable window panel is movable between a closed position, where said movable window panel is disposed at the opening, and an opened position, where said movable window panel is disposed at least partially along said at least one fixed window panel;
a perimeter seal disposed at a surface of said at least one fixed window panel, wherein said perimeter seal comprises a continuous sealing element that circumscribes the opening and that is configured to seal against a surface of said movable window panel about a periphery of said movable window panel when said movable window panel is in the closed position;
wherein said perimeter seal comprises a plurality of elongated sealing portions including an elongated upper sealing portion, an elongated lower sealing portion, a first elongated side sealing portion and a second elongated side sealing portion, and wherein said elongated sealing portions comprise respective elongated sealing lips disposed along respective base portions;
a corner sealing element disposed at a corner region of said perimeter seal at a junction of the first elongated side sealing portion and one selected from the group consisting of (i) the elongated upper sealing portion and (ii) the elongated lower sealing portion;
wherein said corner sealing element extends from an end of said sealing lip of said first elongated side sealing portion and is spaced from an end of said sealing lip of the one of said elongated upper sealing portion and said elongated lower sealing portion, and wherein said corner sealing element extends partially along the one of said elongated upper sealing portion and said elongated lower sealing portion spaced from said sealing lip of the one of said elongated upper sealing portion and said elongated lower sealing portion;
wherein said perimeter seal is formed via a multi-shot injection molding process, and wherein said base portions are formed via a first shot injection molding process and said sealing lips are formed along said base portions via a second shot injection molding process; and
wherein the first shot injection molding process forms said base portions using a polypropylene material, and wherein the second shot injection molding process forms said sealing lips using a thermoplastic elastomer.
