ABSTRACT:
A method and apparatus for applying a coating composition to a surface on at least one panel member using a fastener having the composition on its exterior. The fastener, which has a greater coefficient of thermal expansion, is fitted within the panel member, and during thermally-induced expansion, acts to facilitate diffusion of the composition into the panel surface. The coating composition is applied to the fastener via conventional methods to the fastener, and is engineered to react with the material of the panel member to form, via a diffusion process, an intermediate coating in the region of the panel member and coating materials.
