1. A method of providing an inspection detectable repair to a component, the method comprising:
providing a component to be repaired, the component comprising a substrate having a surface, the component being elongated in a longitudinal direction with a perimeter wall extending longitudinally about a lumen;
identifying a compromised region of a compromised portion of the substrate of the component, the compromised region having at least one void on the surface and extending into the substrate;
providing at least one material to form a filler material to be applied to the surface of the substrate to be repaired;
applying particles of the filler material as a cold spray deposition utilizing a cold spray deposition apparatus, particles of the filler material forming a deposit of cold sprayed particles on the surface of the substrate adjacent to the at least one void; and
wrapping the substrate of the component with at least one layer of wrap material to cover at least a portion of the deposit of the filler material on the substrate.
