A method and apparatus for forming a sealant coating on a fastener are provided. The apparatus comprises a light generator, a light housing, and a forming cup. The light generator is configured to generate light having a number of characteristics that cures the sealant coating on the fastener. The light housing surrounds the light generator. The forming cup is removably connected to the light housing. The forming cup has an internal cavity with an inner mold line complementary to an outer mold line for the sealant coating.

A fabrication method for providing a relatively smooth surface associated with lightning strike protection for composite materials joined with fasteners recessed below the surface is described. The method includes coating at least one of a head of the fastener and a preformed dielectric insert with an adhesive, inserting the preformed dielectric insert into the recess such that the adhesive engages both contours of the recess and the preformed dielectric insert, and removing any excess adhesive from the surface area of the composite material and a top surface of the insert.
