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.

Methods for detecting failure of an adhesive layer

An apparatus and method for selectively decorating a vehicle surface are disclosed. The apparatus is a removable applique with a front face including a graphic comprising ultra-violet responsive material and a back face including an attachment agent having the ability to be applied and removed from the surface of the vehicle without causing damage. The method includes receiving the removable applique on the surface of a vehicle. The method further includes sending an instruction to illuminate an ultra-violet source to direct ultra-violet light at the graphic of the removable applique to render the graphic visible. In one embodiment, the instruction to illuminate the ultra-violet source can be sent in response to the activation of a switch, button, control panel or other input means of controlling the ultra-violet source. In another embodiment, the instruction to illuminate the ultra-violet source can be sent in response to a vehicle state.
