A coating composition comprises a base coat component and a top coat component. The base coat component comprises at least one resin selected from the group consisting of a styrene, a styrene-ethylene/butylene-styrene block polymer and a mixture thereof, and at least one solvent for the resin. The top coat component comprises a Methyl-methacrylate-Acrylate-Methyl-methacrylate block polymer and a solvent for the Methyl-methacrylate-Acrylate-Methyl-methacrylate block polymer. A method of temporarily coating a substrate comprises applying the base coat component to a substrate, allowing the base coat component to dry and applying the top coat component and allowing the top coat to dry. The resulting coating can be removed from the substrate by peeling, even after extended exposure to ultraviolet light.
