Wax lasts about four weeks. A sealant lasts up to about twelve. A ceramic coating lasts years.
Those three numbers are most of the answer, but they are not the interesting part. The interesting part is what those timescales mean for your paint over five years, and it is not what most comparisons say.
What each one actually is
Wax is a natural or synthetic product that sits on top of the clear coat. It fills fine imperfections, adds warmth and depth to the colour, and beads water. It wears off. about 4 weeks is realistic.
A sealant is synthetic, bonds more firmly than wax, and lasts up to about 12 weeks, depending on the specific product, storage, and use. It is more durable and usually a little less warm-looking than a good wax.
A ceramic coating is silica based and bonds chemically to the clear coat. The bond is permanent. What fades over the years is the performance, not the presence.
| Wax | Sealant | Ceramic coating | |
|---|---|---|---|
| Lasts | about 4 weeks | up to about 12 weeks | 3-5 years or more |
| How it attaches | Sits on the surface | Bonds to the surface | Bonds to the clear coat |
| Applications over 5 years | Around 60 | Around 20 | One |
| Times you handle the paint | Around 60 | Around 20 | Once, plus normal washing |
| Cost | Low each time | Low each time | $960 on a sedan |
Wax is not the problem
We would like the industry to stop describing wax as inadequate or bad for paint. It is neither.
Wax does precisely what it was designed to do. On a car that is being sold, or one that comes out a few times a year, or in the hands of someone who genuinely enjoys the ritual of doing it, wax is a perfectly good answer.
The one thing worth understanding is what repeated application costs you, and it is not the money.
That is the case for a coating over wax, and it has nothing to do with wax being a poor product. It is about contact frequency.
When we would recommend wax instead of a coating
We would not.
Asking wax to do a coating’s job is like asking a house painter to use watercolours. Can you? Yes. Should you? No.
If you want watercolours on a wall for a special occasion, you put them over the paint rather than in place of it. Same with wax. Over a coating for a show or a photoshoot, that works nicely. Instead of one, you have chosen a four-week solution to a five-year problem.
When a coating is the wrong spend
That is a different question from which product is better, and the answer is not always a coating.
If you are selling the car soon, you would be paying for protection the next owner enjoys. Twelve weeks of gloss for the sale is all the job needs, and a sealant does that. The same goes for a vehicle you are not keeping long enough for a coating to earn itself back.
That is not us calling a sealant a middle ground. It is not a lesser coating, it is a different product with a different lifespan. What changes in those situations is not which product protects paint better, it is whose paint you are protecting.
Worth being clear about one thing, because it causes real confusion: a sealant is not a ceramic coating. Both get sold as paint protection, and dealer paperwork frequently does not distinguish them. If you were quoted $1,000 for paint protection at a dealership, it is worth finding out which of the two you actually bought. More on that in our dealer protection article.
Cost over five years
| Waxing it yourself | White coating | |
|---|---|---|
| Product | $300 to $500 | $960 |
| Your time | Around 30 hours | None |
| Correction likely at 3 to 5 years | From $500 | Included as preparation at the start |
| Five-year cash total | $800 to $1,000 | $960 |
| Per week | $3.08 to $3.85 | $3.69 to $6.15 |
On cash they land in roughly the same place, and per week they do too. The difference is about 30 hours of your time, and the accumulated marking from handling the paint sixty times rather than once.
If you enjoy the process, the maths is close enough that it comes down to how you want to spend your weekends. That is a genuine choice, not a wrong answer. The full breakdown is in our cost guide. Our pricing calculator will give you a figure for your own vehicle straight away.
In Nelson specifically
The local conditions push the maths further toward a coating, for two reasons.
UV. High for much of the year, and it shows locally as oxidised and peeling paint, especially on red vehicles. Four weeks of wax protection against twelve months of sun is not a fair fight.
Contamination. Bee droppings in spring, bird droppings in summer, blossom and then fruit and then seeds, leaf tannins in autumn, road grime in winter. Coastal salt runs year round, with Rocks Road taking the worst of it.
Every one of those is acidic or abrasive, and every one of them arrives whether or not your wax is still working.
"I asked Aaron to clean windows inside and out on 2 newish Volvos. The haze was impossible to remove. For a very reasonable price did a great job, and the glass is still clear after at least a month."

The short version
Wax if the car is going somewhere special, or being sold, or you enjoy doing it. Put it over a coating if there is one.
Sealant for a few months of protection on a car you are not keeping.
A coating if you want the paint to still look right in five years without spending sixty afternoons on it.
Our benefits article covers what a coating gives you, and the myths article deals with the claims that get overstated in the other direction.
