You will get mixed answers on which wax to use. Since you mentioned you never have waxed a car I would not start off using Zaino as it is a multi-step process. I prefer P21s as it goes on and off like butter and has great depth/shine. It's not as durable as Zaino since that is a synthetic and P21s is pure carnuba but it's so easy to apply I do it every 3 months.
