Common Rust (The Big One)

Lower Quarter Panels

Symptoms

Bubbling, blistering, or perforation on the lower rear quarter panels behind the rear wheels.

Cause

Road spray and mud collect between the inner and outer skins. The trapped moisture causes rust from the inside, invisible until it perforates the outer skin.

Fix

Cut and weld repair sections.

On XP Hardtops, quarter panel repair is particularly expensive due to the complex body shape.

Budget $1,000-2,500 per side.
