A ceramic coating is a liquid polymer that chemically bonds to your vehicle's factory paint. Once cured, it acts as a semi-permanent "sacrificial" layer. It doesn't make your car bulletproof, but it does make it incredibly hydrophobic (water-repellent) and highly resistant to chemical stains from bird droppings, sap, and road salt.
The detailing industry has created a lot of confusion around ceramic coatings. Some shops oversell them as invincible shields; others dismiss them as expensive wax. The truth is somewhere in the middle — and for New Hampshire drivers, it's firmly on the side of "worth it."
