A first car body part to be bonded to a second car body part. The first car body part includes a sealing wall and a supplemental wall having a first side end and a second side end. The sealing wall has a bonding surface to be bonded to a surface of the second car body part. The supplemental wall joins the sealing wall at the first and second side ends forming a void between the sealing wall and the supplemental wall. The joined sealing wall and supplemental wall form a tubular member having a top end and a bottom end. The sealing wall, the bonding surface, the supplemental wall, and the void may be elongated. The first car body part may have a top capping wall and a bottom capping wall, the top capping wall sealing the top end of the tubular member and the bottom capping wall sealing the bottom end of the tubular member, thereby fully enclosing the void. The first car body part may be, e.g., a side body panel, a door interior trim panel, an instrument panel, or a hardware panel. |
