Compositions for reinforcing substrates, reinforced panels manufactured from those compositions, and methods of manufacture are disclosed. A composition may be composed of a base resin binder, a reinforcing fiber, a toughener, a heat curing agent, a cure accelerating agent, a sagging resistance agent, and a reinforcing agent. A coating of this composition can be applied upon a substrate, such as a steel or aluminum substrate. By heating the coating such that the coating cures upon the substrate, a reinforced substrate may be produced. The substrate may be sized and configured as a panel so that it could be used as an automotive panel. The low density and strong characteristics of the cured coating may allow for thin, lightweight automotive panels to be produced which provide higher milage.
