A wax gives warm gloss for weeks, a sealant such as AutoBead Spray Sealant protects for months, and a ceramic coating lasts a year or more but only on properly prepared paint. Choose by how much preparation time you have: a carnauba wax such as ValetPro Indulgence Cream Wax is the most forgiving, a coating the least.
What is the difference between wax, sealant and ceramic coating?
A wax is a natural layer, usually carnauba, that gives warm gloss and lasts weeks to a couple of months. A sealant is a synthetic polymer layer that lasts several months. A ceramic coating cures into a hard silica layer that lasts a year or more, but only on paint that has been properly prepared first.
They are often sold as good, better and best, but sealant vs wax vs ceramic is really a choice between three commitments: of preparation, of maintenance and of how long the protection stays on the paint.
What does a car wax do?
It adds a layer of gloss and protection that sits on the paint and is renewed often. Traditionally carnauba based, a wax is prized for warmth and depth of gloss rather than longevity, and it is the most forgiving to apply: mistakes come off easily.
- Typical durability: weeks to a couple of months.
- Preparation: a clean, decontaminated surface is enough.
- Best for: people who enjoy the process and reapply regularly.
What is a paint sealant?
A synthetic, polymer based protection. It bonds more firmly than wax and lasts considerably longer without a coating's preparation demands. This is the sensible middle ground for most people.
- Typical durability: several months.
- Preparation: clean and decontaminated, correction optional.
- Best for: daily driven cars kept outside.
What is a ceramic coating?
A curing layer, based on silica or similar chemistry, that bonds to prepared paint and hardens. It offers the longest protection and the strongest water behaviour, and it is the least forgiving of the three to apply.
- Typical durability: a year or more, depending on the product and the preparation.
- Preparation: decontaminated, corrected and panel wiped paint, with time for a proper cure.
- Best for: someone willing to do the preparation properly, or to have it done.
The important point about coatings is that the result is decided before the bottle is opened. A coating locks in whatever is underneath it, including swirl marks, and removing a badly applied one means machine work.
Wax, sealant and coating compared
| Wax | Sealant | Ceramic coating | |
|---|---|---|---|
| What it is | Natural carnauba layer | Synthetic polymer layer | Curing silica layer |
| Typical durability | Weeks to a couple of months | Several months | A year or more |
| Preparation | Clean and decontaminated | Clean and decontaminated | Decontaminated, corrected, panel wiped |
| Forgiving to apply | Very | Yes | Least |
| Best for | Gloss and the ritual | Daily drivers | Long protection on prepared paint |
Which waxes and sealants do we stock?
Two waxes, two spray sealants and a ceramic top-up spray. Every product below is in stock with us, and every claim comes from its maker.
Waxes
A liquid cream wax made with carnauba that spreads on and wipes off, which ValetPro says saves time over a traditional hard wax, for a high gloss finish with water beading and UV protection.
A non-abrasive liquid wax polish with carnauba and synthetic polymers. NowRevive says it can be used on its own or as the base for sealants and waxes, on classic and modern paint.
Sealants
A blend of silicone polymers and silica resins that AutoBead rates at 9 months on paintwork and wheels. Spray it onto a microfibre, work it in straight lines on a clean, dry surface, leave it a minute to bond, then buff.
Stjarnagloss Parla Spray Sealant
A water-based nano sealant that Stjarnagloss rates at 3 to 5 months. It can go on dry panels or wet ones straight after the wash, it can be layered, and Stjarnagloss says it makes an excellent wheel sealant.
Ceramic coating
Each coating maker gives its own preparation steps, application temperatures and cure times. Ask the TDHQ team which coating suits your car and the time you have before you buy one.
Keeping it topped up
AutoBead Ceramic Quick Detailer
Nano ceramic particles and reactive polysiloxanes that AutoBead says add a layer of protection lasting about 6 months, on paint, glass, plastics, wheels and trim, used on a dry car or as a drying aid.
Our quick detailer guide compares more top-up sprays, including ones made for ceramic-coated cars.
Is a ceramic spray the same as a ceramic coating?
No. A label saying "ceramic" does not make it a coating.
Ceramic infused shampoos, SiO2 spray sealants and ceramic detailers are maintenance products. They are genuinely useful for topping up water behaviour between details, but they do not cure and bond the way a coating does, and they are not a substitute for one. Sealants and coatings are not interchangeable terms, however loosely the industry uses them.
How do you maintain wax, sealant or a coating?
Wash it gently and top it up. You can top a sealant or a coating with a wax or a spray sealant for extra gloss or slickness, but you cannot use a topping product to rescue poor preparation underneath.
Whichever you choose, maintenance is a pH-neutral shampoo and avoiding harsh traffic film removers on the protected surface. Our guide on how to wash your car safely covers the routine.
Common questions
Can I put wax on top of a sealant or ceramic coating?
Yes. A wax or spray sealant on top adds gloss or slickness and can be renewed whenever you like. It changes how the surface behaves until it wears off, so expect the water behaviour to come from the top layer for a while.
Which is best for a car kept outside all year?
A sealant is the practical choice for most daily drivers kept outside, because it lasts several months and needs no special preparation. A coating lasts longest, but only if the paint is corrected and prepared before it goes on.
Do I need to polish the paint before a ceramic coating?
Yes, if the paint has swirls or scratches you want gone. A coating locks in what is underneath it. Our guide to compound vs polish explains how to correct the paint first.
Choosing honestly
Pick based on how much preparation time you genuinely have, not on the durability figure on the bottle. A well applied sealant on properly prepared paint usually gives a better result than a coating rushed onto a swirled car. If you want help deciding, ask the TDHQ team about your paint's condition and where the car is kept, or browse the full AutoBead range.
