A sealant composition for use in detecting movement between adjoining surfaces of a housing, such as a housing for electronic equipment, is described. The sealant comprises an adhesive, polymeric or paint base in combination with a fluorescent chemical detectable under ultraviolet (UV) light. The sealant composition is applied to the adjoining surfaces in conventional manner to provide a continuous film over the joint, such that tampering with the housing, i.e., opening or attempting to open the housing, causes fracture of the seal between the adjoining surfaces. Visual inspection of the seal under UV light reveals whether the sealant has been replaced. In a preferred embodiment the sealant comprises a mixture of fluorescent materials.
