  • Roof ditch sealing assemblies for vehicles and methods for sealing roof ditches
    Patent number: 10800351
    Abstract: A vehicle includes a roof assembly including a roof having an outer facing surface and a roof ditch that extends below the outer facing surface. The roof ditch extends in a vehicle longitudinal direction between a front windshield and a rear window. A rear roof ditch molding is located at least partially within the roof ditch at a rear portion of the roof ditch. A cured roof ditch sealer extends along a front portion of the roof ditch and rearward in the vehicle longitudinal direction toward the rear roof ditch molding. A roof ditch sealer dam is located between a rear end of the cured roof ditch sealer and a front end of the rear roof ditch molding.

  • Methods for detecting failure of an adhesive layer
    Patent number: 10488324
    Abstract: A method for detecting failure of an adhesive layer applied to first and second surfaces includes inserting a first wedge between the first and second surfaces adhered to one another by the adhesive layer to separate the first and second surfaces by a first predetermined distance, inspecting the adhesive layer for failure when the first and second surfaces are separated by the first predetermined distance, inserting a second wedge between the first and second surfaces to separate the first and second surfaces by a second predetermined distance, and inspecting the adhesive layer for failure when the first and second surfaces are separated by the second predetermined distance.
