Exterior
Its exterior is in great condition with no major dents or scratches. The cloudy patchiness on the upper panels is its clear coating over the aluminium discolouring / peeling from age. This happens on all vintage Airstreams and can be removed by using paint stripper. It could then also be polished to a mirror shine.
