Abstract
A molded plastic automobile body is bonded to a steel frame by depositing an adhesive layer between the body and frame in a circular pattern, to facilitate thermal expansion of the body relative to the frame. To prevent the body from peeling away from the frame, anti-peeling bolts further connect the body to the frame. To diffuse over a large area the downward force of the bolt heads on the plastic body, thereby reducing scalloping of the plastic body, spring washers having large surface areas are sandwiched between the bolts and the body.
