Minor Rust and Corrosion

Rear Quarter Panel Corrosion

Symptoms

Bubbling paint on the rear quarter panels, progressing to perforation. Rust visible inside the boot behind the wheel arch trim. In severe cases, the inner wheelarch structure is completely gone and the outer skin is all that's holding the shape.

Cause

Road spray from the rear tyres is flung up into the space between the inner and outer wheelarch panels. Mud, sand, and moisture sit in this cavity with no way to drain or dry. The steel rusts from the inside out, and by the time paint is bubbling on the outside, the inner structure has been rotting for years.

Fix

Minor surface rust on the outer panel can be treated, sanded, and resprayed ($300-600 per side).

Structural rust in the inner arch requires cutting out the affected metal and welding in new fabricated panels.

This is skilled work and costs $1,500-3,000 per side.

If both rear quarters need major work, the repair bill can exceed the car's value.
