Wheel Arch Rust

Mud, salt and water collect in the folded edge. It often appears first as small bubbles. Rear arches are usually worse. Rubbing tyres, loose arch liners and stone chips damage the protective coating. Small rust spots can be treated, but rust that has eaten through the lip usually needs a welded repair section. Washing salt off the arches in winter slows it down.

Moisture trapped in the seam rusts the metal from inside out.

Fix early to avoid larger repairs. Arch liners help but can trap dirt.
