Unsupported ultra-flush glassrun weatherseal assembly

A weatherseal assembly comprising:

• a generally U-shaped body including a base and first and second L-shaped legs, the first leg having a first portion that only partially overlaps with a first portion of the second leg to form the base of the U-shaped body, and the first and second legs each having a second portion extending outwardly from the first portions of the first and second legs, respectively, to form a glassrun cavity dimensioned to receive an edge of an associated window therein,
• first and second seal lips extending from the first and second legs, respectively, for engagement with opposed, first and second surfaces of the associated window;
• and
• the first leg formed entirely of a first material that is a stiffer/more rigid material than a different, second material that forms the entirety of the second leg and also forms the seal lips, such that at least a first portion of the first material forms the first leg extending outwardly from the base such that a combined thickness of the first leg and the first seal lip is less than 2.5 mm to provide a flush assembly of the weatherseal assembly and associated window.
