We are getting many rat rod owners asking will Rat Wax™ work on their "patina" finishes? YES, it is designed to work on "patina" finishes as well. In case you're unfamiliar with the term" patina", it refers to accumulated changes in surface texture and color that results over time. In other words, it's when the car's finish becomes a mixture of weathered paint, oxidation, primer and light surface rust. Many believe that this is what a "true" Rat Rod is. While it's normally a "natural" mother nature finish, many are now creating a "faux" patina on their project right from the start with unique processes. Either way, Rat Wax™ has got you covered. Rat Wax™will clean and protect your "patina" finish, keeping your ride looking its best. Get yours today!
