I personally never did try the Zano line---And I do believe that it is a good product. However, I have started using Wizards products and their paint sealant and detail spray is really something that you have to witness. I use it on all of my vehicles and I have a black truck, black Impala SS, and a white truck. I buy my stuff by the case from the distributor and save about 30% on the over the counter cost.
