Ceramic coating

Ceramic coating is a liquid product, usually based on silica, that is wiped onto clean, corrected paint where it chemically bonds to the surface and cures into a hard, glass-like layer over the following days. Once cured it is not a topper that sits loosely on the paint the way wax does, it becomes a thin, durable shell over the clear coat.

This matters because that cured layer is far more resistant to UV fading, chemical staining and light scratching than wax or sealant, and it typically lasts one to several years depending on the product rather than weeks or months. It also creates a strongly hydrophobic surface, so water beads tightly and rolls off, carrying dust with it and making the car easier to keep clean between washes.

Because coatings bond permanently to whatever is underneath, any swirl marks or contamination present at application get sealed in as well, which is why correction and thorough decontamination should always happen first. Curing conditions, temperature and humidity, affect how well a coating bonds, so check the product's application window before starting. A common mistake is washing a freshly coated car too soon, before the coating has fully cured, which can leave streaks or reduce durability.
