ABSTRACT:
A process using environmentally friendly materials for restoring a surface of an epoxy graphite composite material that has been degraded by exposure to ultraviolet radiation. An example process includes steps of providing a gelled solvent composition, applying the gelled solvent composition to a degraded surface of an epoxy graphite composite material, and thereafter removing the gelled solvent composition to produce a restored surface. The process uses a novel gelled solvent composition comprising one or more non-halogenated organic solvents, a thickening agent, an abrasive agent, and water; wherein the gelled solvent composition has an evaporative weight loss that is lower than the evaporative weight loss of the one or more non-halogenated solvents.
