A vehicle body part (60) has a perforated grid portion (61) secured in an aperture in a non-perforated portion (601,602), an edge portion of the grid portion defining part of the edge of the body part. A support member (8) extends along the edge portion of the grid portion (60) and supported from the non-perforated portion (601,602), and a seal (9) for contact with an adjacent body part extends around at least said part of the edge of the body part. The seal has a cross-section which includes a first lobe (9c) which covers the edge portion of the grid (61) to protect a vehicle operator from injury by this edge portion and improving styling. The seal cross-section also has a second lobe (9d) which extends between the grid (61) and the support member (8) to prevent vibration of the grid and damage of the paint finish of these components. The seal cross-section also includes a U-shaped channel portion (9a) which encloses the edge of the support member (8).
