Been watching many video reviews of various spray products. Am especially interested in Meguiars Ultimate Quik Wax since I use Ultimate Liquid Wax. Seems to me that all of these products are difficult to apply and do not last very long. Meguiars hybrid ceramic looks easy but you wash most of the product away. Laying down the base coat looks like hard work and no one agrees on how to apply it. Since the benefits last only a few weeks, why bother? It is so easy to apply/remove Ultimate Liquid Wax, why bother with the spray stuff?
