Ceramic coating vs wax in Arizona
Wax isn't bad. It's just being asked to do a job here that it was never built for.

People have waxed cars for a century and it works. In a temperate climate a good carnauba wax gives you a few months of protection and a warm shine, and reapplying it a few times a year is a pleasant Saturday.
Arizona is not a temperate climate, and that's the whole of the argument.
Wax sits on top of your paint. It's a physical layer resting on the clear coat, held there by nothing but contact. It fills fine imperfections, adds warmth to the color, and washes away gradually.
A ceramic coating bonds to the paint. It's a liquid polymer that cures into a hard semi-permanent layer chemically attached to the clear coat. It doesn't wash off. It wears down over years rather than weeks.
That's the difference in a sentence: one is a topping, the other becomes part of the surface.
Carnauba softens at temperatures a parked car in Phoenix reaches routinely by mid-morning. What you apply in April is substantially gone by June — not because you washed it off, but because it melted and ran off.
A ceramic coating is heat stable. Summer temperatures don't degrade it, which is the single reason it makes more sense here than almost anywhere.
Wax you have to reapply every few weeks is protection most people don't actually maintain — and unprotected is where damage happens.
Cost. Wax wins on day one and loses over time. A bottle is cheap; doing it properly several times a year for five years is not, once you count the hours.
UV protection. Ceramic, clearly. This is the damage that actually matters in Arizona, and a layer that survives the summer beats one that doesn't.
Gloss. Genuinely arguable. A fresh coat of quality carnauba on dark paint has a warmth that ceramic doesn't quite replicate. Ceramic gives you sharper reflections and more depth. Some people prefer wax on a show car — that's a taste question, not a performance one.
Ease of cleaning. Ceramic, by a distance. Dirt releases rather than clinging, which means less contact with the paint, which means fewer swirl marks over time.
Effort. Wax is a recurring commitment. Coating is one appointment and then normal washing.
Paint sealants are the middle option — synthetic rather than natural, more heat tolerant than carnauba, typically four to six months in this climate. Better than wax here, well short of a coating.
If you're not ready for coating, a sealant is a reasonable step. It's still something you'll be redoing two or three times a year.
Neither stops a rock chip. Wax, sealant and ceramic all protect against UV, chemicals and light marring. None of them absorb impact.
That takes paint protection film, which is a physically thick urethane layer rather than a surface treatment. Anyone selling you a coating as chip protection is overselling it.
If you're selling the car this year, wax it. If it lives in a garage and does low miles, you have less to protect against. If you enjoy the ritual of waxing a car on a Saturday — and plenty of people do — that's a completely legitimate reason, and we're not going to talk you out of it.
Wax is a good product being asked to do something Arizona won't let it do. It'll protect your paint for a few weeks at a time, and if you're the kind of person who genuinely reapplies it every month, you'll be fine.
Most people aren't. Most people wax in spring, mean to do it again, and don't — which leaves the paint unprotected through exactly the months that cause damage. That's the real argument for coating: not that it's better in a lab, but that it keeps working when you forget about it.
