Rust is a common problem that affects most car owners. It is caused by the reaction between metal and moisture, which leads to corrosion. Rust can cause serious damage to your car’s body and should be repaired as soon as possible to prevent further damage. The traditional method of repairing rust is welding, but not everyone has the necessary equipment or expertise to carry out welding repairs. Fortunately, there are alternative methods for how to repair rust on your car without welding.
In this article, we will guide you through the steps to repair rust on your car without welding, including the tools and materials needed, different grit sandpaper, and helpful tips and tricks.
How Can I Prevent Rust On My Car
Regularly washing and waxing your car can help prevent rust buildup. You can also apply a rust preventative spray or wax to vulnerable areas, such as the undercarriage. Avoid parking your car in areas with standing water or salted roads, as these can accelerate rust formation. If you live in an area with high humidity, consider using a dehumidifier in your garage to reduce moisture buildup.
How Do I Know If My Car Has Rust
Rust typically appears on the surface of the car as brownish or reddish patches. However, it can also be hidden beneath paint or body filler. To locate hidden rust spots, use a magnet to check for areas that are not magnetic. These areas may be rusted and require attention.
What You Will Need
Before we dive into the steps to repair rust on your car, here are some tools and materials you will need:
- Rust converter
- Rust inhibitor
- Body filler
- Sandpaper (120-grit, 220-grit, 320-grit)
- Masking tape
- Paint (matching your car’s color)
- Paint primer
- Clear coat
How to Repair Rust on Your Car Without Welding
Step 1: Remove Rust
The first step in repairing rust on your car is to remove the rusted area. Use sandpaper with a grit of 120 to sand the rusted area until you reach bare metal. Be sure to wear a mask or respirator to protect yourself from inhaling the rust particles. Sand in a circular motion until the rusted area is completely removed. Use a wire brush to remove any loose rust or debris that may be present.
Step 2: Apply Rust Converter
Once the rusted area is sanded down, apply rust converter to the area. Rust converter is a chemical solution that converts rust into a stable compound. It also helps to prevent rust from spreading. Apply the rust converter according to the manufacturer’s instructions, usually by brushing or spraying it onto the affected area. Allow the converter to dry completely before proceeding to the next step.
Step 3: Apply Rust Inhibitor
After the rust converter has dried, apply rust inhibitor to the affected area. Rust inhibitor helps to prevent the rust from returning. Apply the rust inhibitor according to the manufacturer’s instructions, usually by brushing or spraying it onto the affected area. Allow the inhibitor to dry completely before proceeding to the next step.
Step 4: Apply Body Filler
Once the rust has been removed and the converter and inhibitor have been applied, it’s time to apply body filler to the affected area. Body filler is used to fill in any holes or gaps that may be present in the metal. Apply the body filler according to the manufacturer’s instructions, usually by mixing it with a hardener and then spreading it onto the affected area with a putty knife. Allow the body filler to dry completely before proceeding to the next step.
Step 5: Sand the Body Filler
After the body filler has dried, use sandpaper with a grit of 220 to sand down the body filler until it is smooth and even with the surrounding metal. Sand in a circular motion until the body filler is level with the surrounding metal. Then, use 320 grit sandpaper to further smooth the surface of the body filler. Be sure to wear a mask or respirator to protect yourself from inhaling the sanding dust.
Step 6: Mask the Area
Before painting, it’s important to mask off the surrounding area to prevent overspray. Use masking tape to cover any areas that you don’t want to be painted, such as the windows or trim.
Step 7: Apply Primer
Once the area is masked off, apply primer to the affected area. Primer helps the paint to adhere to the surface and also helps to prevent rust from returning. Apply the primer according to the manufacturer’s instructions, usually by spraying it onto the affected area. Allow the primer to dry completely before proceeding to the next step.
Step 8: Paint the Area
After the primer has dried, it’s time to paint the affected area. Use paint that matches your car’s color for the best results. Apply the paint according to the manufacturer’s instructions, usually by spraying it onto the affected area. Apply several thin coats, allowing each coat to dry completely before applying the next one. Be sure to wear a mask or respirator and work in a well-ventilated area when painting.
Step 9: Apply Clear Coat
Once the paint has dried, apply clear coat to the affected area. Clear coat helps to protect the paint from the elements and gives it a glossy finish. Apply the clear coat according to the manufacturer’s instructions, usually by spraying it onto the affected area. Apply several thin coats, allowing each coat to dry completely before applying the next one.
