A method for bonding sidewall panels each comprising first and second skins and a core member sandwiched therebetween. The first skin has a main portion and an overlapping portion extending beyond the core member. The second skin has a main portion and an overlapped portion not extending beyond the core member. The method comprises the following steps. First, an entire exterior surface of the first skin and only an exterior surface of the main portion of the second skin of each of said sidewall panels are painted. Then, the sidewall panels are oriented such that the overlapping portion of the first skin of one sidewall panel is planarly aligned with the overlapping portion of the second skin of another sidewall panel. Next, the overlapping portion of the first skin of one sidewall panel is adhesively bonded to the overlapped portion of the second skin of another sidewall panel.
