Understanding the Enemy: What Causes Chassis Rust?

Assessment and Preparation
-
Thorough Inspection: Begin by thoroughly cleaning the chassis with a pressure washer and degreaser. This will reveal the full extent of the rust damage.

Safety First: Wear safety glasses, gloves, and a respirator to protect yourself from rust particles and fumes during the repair process.

Priming and Painting: Once the filler is dry and sanded smooth, apply automotive primer followed by a top coat of paint that matches your car’s color.

Undercoating: Applying a rust-proofing undercoating will further protect the repaired area and prevent future rust formation.
