The method may also include positioning the tip end of the repair tool adjacent to a defect (106) of an internal component (104), wherein the defect defines a fi liable volume (108) along a portion of the internal component. In addition, the method may include intermixing two or more constituents of a repair agent (128) within the repair tool at a mixing location (113) defined within the gas turbine engine, and expelling the repair agent from the tip end such that the fillable volume is at least partially filled with the repair agent.
