The result of the Renwax application is not obviously significant in the photos. I can tell an improvement in hand however. Perhaps the desert patina is too coarse for the wax. Or perhaps I applied too little Renwax (although I applied it liberally). Nonetheless, I am happy with the final result. Top picture: Uncleaned; as purchased. Middle picture: After cleaning but pre-Renwax. Bottom picture: After Renwax application.
