Abstract

A method of adhering a first component to a second component includes priming the first component with an adhesive bond primer containing a primer material, a corrosion inhibitor, and a chemical additive (such as a dye compound), and using an adhesive to attach the second component to the first component through the adhesive bond primer applied on the surface of the second component. The chemical additive allows inspection of the adhesive bond primer with a corresponding radiation source.
