A ceramic coating can temporarily lose some of its water-repelling behavior without actually breaking down. Contamination, surface residue, improper washing, and environmental buildup can cover the coating's active surface, making water spread rather than bead even when the underlying protective layer remains intact. For drivers in Saint James, NY, seasonal weather can contribute to this effect. Rain, road salt, pollen, tree residue, and airborne contaminants can accumulate on a vehicle throughout the year, particularly when the vehicle is parked outdoors. Why Does Ceramic Coating Become Less Hydrophobic? Hydrophobic behavior depends on the ceramic coating's exposed surface interacting with water. When that surface becomes covered with mine…
