303 Protectant protects any color plastic, rubber, vinyl, fiberglass or sailcloth from the damaging effects of ultraviolet rays. 303 Protectant works great on boats, penetrating the colored gelcoat to restore a like-new finish. Protects new finishes from oxidation caused by UVS exposure. Excellent on RV's, convertible and vinyl tops, rubber bumpers, dashboards and woven polyester. Surfaces treated with 303 protectant repel dirt, dust, oils, and all oil based stains! Safe for rubber, plastic, clear and solid color vinyl, glass and paint (16 oz spray bottle)
