Hello, I am not really a car care fanatic, but in the upcoming spring I would like to treat my car to something. In summer I always wash the car by hand, in winter I drive then 1-2 times into the washing machine. Otherwise there is no extra care for the car. Now it becomes 2 years old and I thought I could do something good then my car. However, I don’t look all the way through. Is then a polish enough? Or even just growing? Or does it have to be both ?
