My car's 1980's lacquer lives by Zaino. When I got it, it had a normal wax job complete with swirls. After a wash with Dawn and a good claybar job, the paint looked every bit of its 25 years. If not for the chips and scrapes you would never know how old and tired the paint is, Zaino really brings it back.

It is even resistant to mulberry-filled bird droppings.

First and second pic are after Zaino.

Third pic is before.
