Spray-On Ceramic: This is an easy-to-use, water-based spray-on ceramic coating. It greatly enhances the gloss and slipperiness of the surface, while creating a hydrophobic (water beading and sheeting) effect that can last up to 1 year. Spray-On Ceramic Coating can be used as a topper, on previously ceramic coated vehicles or on a non-ceramic coated vehicle surface. Use on Paint, Glass, Plastic and Rubber.
