A process has been developed for treating plastic and plastic composite materials wherein a protective epoxy coating is placed on said material by contacting with a composition comprising an epoxy resin, an effective amount of curing agent for the epoxy resin, an alcohol and a hydrocarbon solvent. In another embodiment, the protective epoxy coating is applied by a process comprising the sequential contacting of the plastic or plastic composite surface with a first hydrocarbon solution comprised of an epoxy resin and a hydrocarbon solvent, and a second hydrocarbon solution comprised of an alcohol, a curing agent, and a hydrocarbon solvent.
