In this article, we’ll take you through the steps of repairing car rust and restoring your vehicle to its former glory.
What Causes Car Rust?
Before we dive into the process of fixing car rust, it’s important to understand what causes it in the first place. Rust occurs when iron or steel is exposed to oxygen and moisture over time, resulting in a chemical reaction that eats away at the metal. Cars are particularly vulnerable to rust as they’re constantly exposed to the elements, such as rain, snow and salt on the roads. Rust can also develop on cars that have been in accidents or have been poorly maintained.
Tools and Materials You’ll Need
Repairing car rust requires a few essential tools and materials. Here’s a list of what you’ll need:
- Sandpaper (80 and 220 grit)
- Rust converter
- Body filler
- Putty knife
- Sanding block
- Primer
- Spray paint (matching your car’s color)
- Clear coat
Step-by-Step Guide to Repairing Car Rust
Follow these steps to fix car rust:
- Identify the Rust: Check your car thoroughly for any visible signs of rust. Look for discolored or bubbled paint, as these are telltale signs of rust underneath.
- Clean the Area: Use soap and water to clean the area around the rust. Make sure it’s completely dry before moving on to the next step.
- Sand the Area: Use 80-grit sandpaper to sand the affected area until you reach the bare metal. Then, use 220-grit sandpaper to smooth out the edges.
- Apply Rust Converter: Apply rust converter to the sanded area, following the manufacturer’s instructions. This will stop the rust from spreading and prepare the metal for the next step.
- Apply Body Filler: Apply body filler to the area using a putty knife. Smooth it out and let it dry according to the manufacturer’s instructions.
- Sand the Area Again: Use a sanding block with 220-grit sandpaper to smooth out the body filler until it’s level with the surrounding metal.
- Apply Primer: Apply primer to the area, following the manufacturer’s instructions. Let it dry completely.
- Spray Paint: Spray paint the area with a color that matches your car. Apply several thin coats, letting each coat dry before applying the next.
- Apply Clear Coat: Apply a clear coat over the paint to protect it from further damage. Let it dry completely.
- Buff and Polish: Use a polishing compound and buffing pad to polish the area until it’s smooth and shiny.
