1. A fluid applicator for applying a fluid to a surface protrusion, said applicator comprising a hollow body having an elongated axis with opposing ends and an opening at each of the opposing ends, a first porous material positioned inside said hollow body along the elongated axis containing a small female aperture and a second porous material abutting the first porous material containing a larger female aperture relative to the aperture in the first porous material, the larger aperture being formed to a predetermined depth and geometric shape so as to allow the larger aperture and the second porous material to cover a male protrusion of a given height and geometric shape such that fluid uniformly flows from the second porous material to the protrusion, an elongated pin positioned between the opposing openings and extending through the small aperture of the first porous material into the larger aperture of the second porous material, the pin extending into a female opening in the male protrusion as the large aperture covers the protrusion such that fluid flows from the second porous material along the elongated pin into the female opening in the male protrusion.
