A water based spray wax composition containing a microemulsion of a cationic wax nanoparticles, a quaternary silicone compound and zinc oxide nanoparticles providing long lasting protection of paint, glass, and metal, plastic, rubber, or elastomeric trim surfaces. The use of microemulsions or nanometer sized particles in the primary ingredients provides a transparent spray wax composition, which provides excellent coverage due to a significantly larger surface area, due to the nanoparticles used in the formulation. It also enables the wax particles to penetrate and fill small cracks and crevices for improved appearance, and durability of the spray wax properties. Because of their small size, nanometer sized particles do not reflect light which passes though the coating without any, or a minimal, amount of reflection resulting in a visual appearance of the liquid being transparent and eliminating hazing, streaking, and swirl marks associated with conventional spray wax products utilizing ingredients composed of conventional sized particles.
