The chemical-resistant foils and tapes that were used to protect the windows, fiberglass, brite-work, engine inlets, actuators, door seams and all other openings in the aircraft are removed, exposing a considerable area of unstripped surface.

The areas that were protected by the foil now have to be sanded, by hand. This easily can take 4 people a week or more to complete on a small single-engine aircraft.
