Methods of applying materials over fastener heads protruding from non-horizontal surfaces

Abstract:

A method of applying a material over a fastener head, protruding from a non-horizontal surface of a part, the method comprising advancing an applicator toward the non-horizontal surface, pressing a sealing rim of an enclosure against the non-horizontal surface, at least partially filling the enclosure with the material, and retracting the applicator away from the non-horizontal surface to asymmetrically distribute the material across the fastener head.
