TOYOTA 4RUNNER RUST PROTECTION

Built to last. Protect it from the start.

WHY PROTECT YOUR TOYOTA 4RUNNER?

The Toyota 4Runner is famous for reliability and resale value, but even the toughest SUVs need rust protection in New England. Salt, brine, and trapped moisture attack the frame, rear quarters, and lower body seams over time.

4Runners are often driven through snow, mud, and off-road conditions. The boxed frame and rear body panels can collect salt and moisture, especially around the wheel wells, rear quarters, and sunroof drain channels. Protecting these areas early helps preserve the 4Runner's legendary longevity.

COMMON RUST-PRONE AREAS

Frame Rails

The 4Runner's full frame is strong but collects salt and moisture inside boxed sections and around mounts.

Rear Quarter Panels

Rear quarters and wheel arches are common rust spots where salt spray and debris accumulate.

Rocker Panels

Lower body seams and rockers trap moisture and are vulnerable to rust from the bottom up.

Sunroof Drain Channels

Clogged or leaking drains can let water collect inside the body and cause hidden rust.

Underbody Skid Plates & Mounts

Off-road and trail protection hardware can hold moisture against the frame if not coated.
