Nu Finish Once-A-Year Car Polish (16 oz)

Most car polishes demand shade, careful technique, and a lot of elbow grease. Nu Finish Once-A-Year Car Polish takes a different approach — this 16 oz liquid uses zinc cross-linking polymers instead of wax, and it goes on without rubbing or buffing. You can even apply it in direct sunlight without worrying about streaking or residue.

Nu Finish claims protection that lasts up to a year, or roughly 52 car washes, from a single application. The zinc polymer formula bonds to the paint surface differently than traditional carnauba or synthetic wax. Water continues to bead well for months after application, protecting against road chemicals, tree sap, bird droppings, and UV-driven oxidation. The 16 oz bottle is enough for multiple applications on a standard-sized vehicle.

Beyond cars, this polish works on fiberglass boats, RVs, motorcycles, and chrome surfaces. If you have been spending weekends re-waxing every few months, this is worth trying as a lower-maintenance alternative.
