Rust Repair for King City Trucks and Cars

It starts at the chip

Rust needs bare steel and salt, and King City supplies both. The gravel drive and the sideroads chip the paint off the lowest, most forward surfaces — the rocker behind the front wheel, the leading lip of the rear arch, the bottom of the doors, the cab corners on a pickup — and winter brine works into every chip once the salt trucks start running the hills. Each spot fails for its own reason. The arch lip is a hem, two layers of steel folded together, and brine wicks into the fold and sits there. The rocker is a closed box with drain holes, and once the holes silt up with sand from the drive it holds water. The dogleg is where the rear tire fires grit at the paint all winter. A pickup adds the bed sides above the wheel and the tailgate seam.

What makes King different is how the vehicles live. The truck that drags the horse trailer, plows the drive and runs to the feed store sits outside on gravel all winter and rarely sees a wash. The second car — the GO run to Union, the Seneca drop-off, the one a teenager inherits for the run to school — spends the salt season on the same drive while the newer SUV takes the garage bay. Both are candidates by their sixth winter.

What holds on a gravel drive: welded steel and a waxed cavity

There is only one repair that holds: remove the rusted steel and replace it. The cut runs outward from the rot until the edge is bright and thick enough to weld. New steel goes in — a stamped rocker or arch section when one is made for the vehicle, a hand-formed patch when it is not — and is welded along the seams, then ground smooth. Seam sealer closes the joints, and a wax is fogged into the cavity behind the repair so moisture cannot restart the process from inside. Primer, colour tinted to the panel and a blend across the door and quarter close it out, with the refinish warranted for life. Grinding the bubbles and filling over them is not something we do; the rust keeps growing and the paint lifts within two winters.

Trucks often get a practical variation: a rocker or cab corner repair finished with a textured bed-liner coating rather than colour, which stands up to gravel far better and is honest about what the truck is for.

• Cut back to bright steel; no filler over rust
• Stamped or hand-formed steel welded in, seams sealed, cavity waxed
• Colour-matched blend, or a textured coating on a working truck

A September job, and one trip

Rust is not insurable. No comprehensive or collision policy treats corrosion as anything but wear, so the number our estimator gives you is what you pay, and it is built from three factors: how much steel has to come out, whether a stamped section exists for the model or has to be formed by hand, and how far the refinish has to extend. The work runs days, not hours, and the panels have to be here before you are. Our estimator reads your photos — the underside of the rocker, the inside of the arch lip with a flashlight, the cab corner from below — writes the estimate, orders the metal, and only then asks you to make the drive. Pickup is set when the paint has cured.

September is the month. The gravel of spring has done its work, the salt has not started, and a truck that goes back to King with sealed rockers and waxed cavities meets the brine with a closed skin. If the vehicle is coming down anyway on a collision claim or for paint, the rust goes on as a separate line and gets done in the same stay, which is the best use of 34 kilometres.
