How to Fix Rust Damage on a Car
Rust is created when bare metal is exposed to both oxygen and water. This creates iron oxide, better known as rust. Rust eats away at the surrounding metal, which can cause connection problems and over time makes the vehicle less structurally secure as the rust penetrates the vehicles steel crumple zones. Immediate action is required as soon as the rust appears to stop it from spreading throughout the entire car body.
Instructions
- 1
Remove any loose rust from the car with the wire brush. Keep using the wire brush until the bare metal underneath the rust shows through.
2Mix the fiberglass paste included in the repair kit with the correct amount of hardener. Use a putty knife to apply the mixed paste behind the rust holes. Be sure to press the paste securely into the rust damage.
3Wait for the paste to harden, then use the sandpaper to sand off any excess paste or rust debris.
4Mix together the body filler and hardener, then spread over the rust-damaged area. Wait for the filler to harden, then use sandpaper to sand the area smooth.
5Use a solvent wipe to remove any dust or grease from the area. Shake the primer can to mix the paint, then apply the first coat of primer over the damaged area.
6Wait for the primer to dry, then sand the area. Apply a second coat of primer and wait for it to dry. Then sand again. Repeat this process until the primer surface is even with the rest of the cars paint.
7Spray a few thin coats of the topcoat paint over the primer area. Wait for the topcoat to dry, then polish it with a polishing compound to blend the paint into the rest of the cars paint.
