Abstract
A method for repairing ballistic impact damage to structural panels of vehicles comprising the steps of cutting out the damaged area in the panel in a preselected size circular cutout, bending a circular patch including an exterior circular metal sheet laminated to a smaller circular interior cloth layer to match the surface convolutions of the panel, impregnating the interior cloth layer with resin and attaching the patch to the panel. In this manner the patch is bent to fit before impregnation and is fixed to the bent shape by fixing the cloth layer.
