Ceramic Coating makes any surface it is applied on Hydrophobic, we strongly recommend including this to your vehicle's wheels, paint, and glass. Once applied, those surfaces will repel water making cleaning your car easier than ever. Depite myths in the industry, Ceramic Coatings do not protect your car from rock chips or other forms of road debris. If you are looking to protect your vehicle, we reccomend applying Paint Protection Film (PPF) or a Vinyl Wrap.
