Make your engine look new again. Engine Brightener refreshes and rejuvenates tired wrinkle black finishes on engine cases, cylinder fins, covers or anywhere else the color has faded or lost its luster. Formulated with high-temperature silicon polymer, this detergent-resistant finish restorer cleans deep into the wrinkle black surface and "moisturizes" the finish to return the original satin sheen. Just spray it on, let it soak in and wipe away for a fresh look. 11 oz (311 g) Aerosol Can.
