Abstract

An anti-fuel-leak, plural-layer barrier coating applicable to the outside surface of the wall in a liquid-fuel container possessing a layer stack including plural, cooperating, barrier layers, each formed of a high-elastomeric material which reacts with a material-swelling behavior on contact with fuel of the type contained in the container, and, among these plural layers, at least one cast-formed layer. Associated methodology involves applying directly onto such a surface, by one only of the processes including casting and spraying, an inner layer formed of the mentioned high-elastomeric material, and thereafter forming, outwardly of the applied inner layer, and also of the same high-elastomeric material, another layer by the other one only of the two, mentioned processes. Selectively, the layer formed by spraying may include a population of spray-introduced, liquid-fuel imbiber beads
