Abstract
A method for treatment of two surfaces, each surface belonging to a metal part which is designed to be painted, the two surfaces being secured adjacent to one another or one on top of the other. The treatment method comprising a sandblasting step during which each surface is subjected to sandblasting, a projection step during which each surface thus sandblasted is subjected to thermal projection of an aluminum alloy, such as to compensate for the divergences between the two surfaces, and a finishing step during which the layer of aluminum alloy thus projected is subjected to mechanical finishing, such as to constitute a coating with a homogeneous surface.
