Abstract: A method of assembling a part for a motor vehicle is shown. The method comprises the steps of providing at least one of the parts with a first adhesive for bonding with the other part, the first adhesive being activated under the effect of a first predetermined condition, providing at least one of the parts with a second adhesive for bonding with the other part, the second adhesive being different from the first adhesive and suitable for activating under the effect of a second predetermined condition different from the first predetermined condition. The parts are then assembled together by the first adhesive by exposing the parts to the first predetermined condition in such a manner as to define a mutual relative position of the parts in the assembled part, and in the absence of the second predetermined condition, and the assembled-together parts are exposed to the second predetermined condition.
