What ceramic coating actually does
A ceramic coating is a liquid that bonds to your car's clear coat and hardens into a thin, glassy layer. It makes the paint slick and water-repellent, so dirt and bird droppings wash off more easily, and it protects against UV fading, which matters under New Zealand's strong sun.
What it doesn't do: it won't stop stone chips or deep scratches, and it doesn't mean you never wash the car again.
How long does ceramic coating last?
Most professional coatings last about 2 to 5 years, depending on the product, how well the paint was prepared, and how the car is looked after. Gentle hand washing and avoiding automatic brush washes make the biggest difference to how long it lasts.
Ceramic coating vs wax
- Wax sits on top of the paint and lasts weeks to a few months. It's cheap and easy, but needs reapplying often.
- Ceramic coating bonds to the paint and lasts years. It costs more up front and needs proper paint preparation first.
Over several years, a coating can work out better value than regular waxing, especially if your time matters.
Why paint correction comes first
A coating locks in whatever is underneath it, including swirls and scratches. That's why a good installer polishes the paint first. If a quote seems cheap, check whether paint correction is included.
Is it worth it for you?
Worth it if: your car is new or in good condition, you plan to keep it for a few years, it lives outside, or you want easier washing.
Probably not if: you're selling soon, the paint is badly damaged, or you only ever use automatic car washes.
Frequently asked questions
Can I put ceramic coating on an older car?
Yes, if the paint is in reasonable condition. It will need paint correction first, which adds to the job but makes a big visual difference.
Do I still need to wash a ceramic coated car?
Yes. The coating makes washing faster and easier, but dirt still builds up. Hand washing every couple of weeks keeps it performing.
Does ceramic coating protect against scratches?
It adds light resistance to fine marks, but it won't stop stone chips or deep scratches. Paint protection film is the option for that.
