Panel reinforcement structure for automobile bodies including a wide outer skin such as a roof panel, a bonnet and a trunk lid, and one or more reinforcement members for applying the skin with a rigidity. The reinforcement member is applied to the outer skin with one or more layers of a mastic sealant. A layer of open cell type elastic foamed material is provided between the mastic sealant layer and one or each of the outer skin and the reinforcement member for the purpose of allowing a relative movement between the outer skin and the reinforcement member to avoid any distortion of the outer skin due to a difference in thermal expansion.
