Minor Rust and Corrosion

Floor Pan Corrosion

Symptoms

Soft or perforated floor pans. Visible rust when the carpet is lifted. In extreme cases, you can see the road through the floor.

Cause

Road spray, trapped moisture, and minimal factory undersealing. Cars that have spent time on unsealed roads, or been parked on grass or dirt, accelerate floor pan corrosion.

Fix

Surface rust: wire brush, rust converter, and underseal.

Perforation: cut and weld new steel sections.

Full floor replacement is a major job requiring a hoist or rotisserie.

Cost: $500-1,500 for localised repair, $2,000-5,000 for extensive floor work.
