What is the product you are asking about? If you have Zaino on your car, isopropyl alcohol will remove it. No wonder the car doesn't feel very slick - you are taking off all your Zaino! I have some Meguiars quick detailer for a non-Zaino car that seems to work well. It was only $5 for a big bottle at my local auto parts store. Haven't tried it on a Zaino'd car, though I am sure it will product similar effects (except dust reduction).
I just bought a case of Z6 because I use it so often. Miracle complement for Zaino polish, IMO.
