This stuff. I always had to order it online. Worked like a champ on faded fenders/trim and lasted longer than any type of tire-shine product, as this product is actually black. More like a deep-penetrating dye, so I only had to apply it maybe twice a year. Made a 30yr old Jeep look nearly new again after I painted the metal trim, buffed down the old clearcoat, and treated all the plastic with ReNu.
