the gap 58 when the depending leg 64 is engaged in the cured urethane mass 60 this result does not occur in a non epdm elastomeric molding at a small radius bend instead and as illustrated in fig1 and 11 along a small radius bend or turn the inner edge of the crown crimps as at 66 due to compression while the outer edge stretches as at 68 which results as shown in fig1 in the outer crown portion 70 lifting out of contact with the auto body 72 and failing to effectively serve as a weather barrier seal to overcome this prior art short coming the prior art practice is to use a mitered joint 20 at the windshield lower right and left corners 18 as a patentable advance it is herein proposed to embody corner shapes in the molding 10 at locations coinciding with the windshield corners 30 and 34 thereby obviating the need to use mitered joints said corner shapes are readily made by hand in epdm elastomeric material of a type which at 70 durometer exhibits a nominal resistance to shape change from its extruded shape and which heretofore has not been known for use as an auto reveal molding more particularly epdm is the acronym for ethylene propylene di monomer elastomeric material and is commercially available from colonial rubber works inc of dyersburg tenn and like sources of compound polymers epdm elastomeric materials at significantly high durometer characteristics e g 90a durometer are described along with extrusion instructions in u s pat no 5 311 711 issued to julio desir sr for 34 j type window lace assemblies 34 on may 17 1994 but are too inelastic for practicing the.
