Ceramic coating vs wax

Is a coating worth it over a good wax?

A wax sits on top of the paint and washes away in a few months. A ceramic coating bonds to the clear coat and lasts years. Wax costs less and has to be redone; a coating is applied once, over corrected paint, and changes how often the vehicle needs washing.

Side by side

  • How long it lasts

    Wax or sealant

    Weeks to a few months, then it is gone and the paint is bare again.

    Ceramic coating

    Years. It is a semi-permanent bond with the factory paint, not a layer resting on it.

  • How it goes on

    Wax or sealant

    Wiped on over clean paint. Quick, and it can be redone at home.

    Ceramic coating

    Applied once in the shop over corrected paint, then cured. It is not a driveway job.

  • Gloss

    Wax or sealant

    Warm shine that fades as the wax wears off.

    Ceramic coating

    Depth and clarity a wax cannot give, on black paint and white paint alike.

  • Washing

    Wax or sealant

    Normal washing, at the normal interval.

    Ceramic coating

    Water and dirt slide off, so the vehicle stays clean longer and washes in less time. It is not self-cleaning; it makes cleaning quick.

  • Rock chips

    Wax or sealant

    No protection.

    Ceramic coating

    No protection. Neither one stops a stone. That is what paint protection film is for.

  • Prep needed first

    Wax or sealant

    Decontamination. Clay and iron removal come before any wax, sealant or coating.

    Ceramic coating

    Decontamination and paint correction, so the coating locks in corrected paint rather than sealing swirls under it.

  • Cost

    Wax or sealant

    Low each time, repeated forever.

    Ceramic coating

    Higher once: from $1,650 for the Entry tier. Oka confirms it after he sees the vehicle.

  • Who it suits

    Wax or sealant

    Someone who enjoys doing it, or a vehicle being sold soon.

    Ceramic coating

    Someone keeping the vehicle, who would rather wash it less and have it look better while they do.

What Oka tells people

If you like spending a Saturday on the vehicle, wax is genuinely fine, and doing it properly beats a coating applied over dirty paint.

If the vehicle is one you are keeping, a coating is the better spend, because the cost is paid once and the correction underneath it is permanent. The reason a coating looks better is mostly the correction: the swirls come out first, and then the finish is locked in that way.

Neither one stops a rock chip. If chips are the worry, the answer is film on the front, and many owners do film on the front and a coating everywhere else.
