Adam cleaned and conditioned the leather of his 1974 Mercedes 450SL. The leather was old and marked, especially noticeable were sunscreen marks. After cleaning it with the leather cleaner and the bush section by section, being careful around any cracks so as not to spread them but pretty vigorous on non - cracked areas , wiping won’t with a brown microfiber as he went, he then applied leather conditioner with the brown workhorse applicator, waiting a while before buffing off the excess. He repeated a few times on the really dry and cracked areas light the steering wheel. After finishing everyone said it looked like he had reupholstered the car. He was super happy.
