All depends. Everything is done by hand with various techniques. What color car do you have, do you have leather? If you have a lighter colored car I will start with Zaino Z-7 to clean the car. Then I would usw Zaino Z-2 pro to polish it. It all really depends. If you have swirls or not, or if I need to clay bar it. Tell me what color, whate shape the paints in, what interior, and if you prefer a certain product.
