Abstract

Provided are methods and systems for applying materials at interface areas formed by fasteners and parts. Specifically, a material is delivered to an interface area such that at least a portion of a fastener remains free from this material. The interface area may be sealed such that the material is contained within that area. As such, a controlled amount of the material is dispensed in a precise location. An applicator used for this process may include a housing and inner guide slidably disposed within this housing. The material may be delivered through an annular flow channel between the housing and inner guide. The inner guide may be sealed against and, in some embodiments, centered with respect to the fastener. The housing may be sealed with respect to the part and, in some embodiments, may be rotated with respect to the part to redistribute the material at the interface area.
