Abstract

Described herein is an apparatus for treating a surface defect on a target surface. The apparatus includes a pump having a housing that defines a chamber for storage of a surface defect treatment composition and an applicator having an orifice in fluid communication with the chamber. The pump and the applicator are positioned such that the pump housing is manually compressible to directly deliver surface defect treatment composition from the chamber to a target surface defect on a surface by way of the orifice.
