Ceramic protection bonds to the clear coat, creating a hydrophobic, low-friction surface that resists contamination and makes washing dramatically easier.
There are two broad categories — dedicated ceramic coatings that last years, and ceramic spray sealants that last months. Both are excellent when applied correctly.
Ceramic protection is not a force-field. It doesn't stop stone chips or scratches. But it protects against chemical staining, UV and bonded contaminants, and it looks stunning.
