How to Repair Car Body Rust Hole
Materials You’ll Need
- Sandpaper (120-grit, 320-grit, and 600-grit)
- Wire brush
- Rust converter
- Bondo or metal filler
- Sanding block
- Primer
- Paint
- Clear coat
Step-by-Step Instructions
1. Prepare the area
Start by cleaning the area around the rust hole with a wire brush to remove any dirt or debris. Then, use sandpaper to sand the area around the hole until the metal is smooth and free of rust.
2. Apply rust converter
Next, apply a rust converter to the area around the hole. This will help to stop the rust from spreading. Allow the rust converter to dry according to the manufacturer’s instructions.
3. Fill the hole
Once the rust converter has dried, you can fill the hole with Bondo or metal filler. Use a putty knife to apply the filler, and smooth it out so that it is level with the surrounding metal. Allow the filler to dry according to the manufacturer’s instructions.
4. Sand the filler
Once the filler has dried, sand it smooth with a sanding block. Start with 120-grit sandpaper, and then move to 320-grit sandpaper. Finally, finish with 600-grit sandpaper.
5. Prime the area
Once the filler has been sanded, prime the area with a primer. This will help to protect the metal from rust and will provide a base for the paint. Allow the primer to dry according to the manufacturer’s instructions.
6. Paint the area
Once the primer has dried, you can paint the area with a paint that matches the color of your car. Allow the paint to dry according to the manufacturer’s instructions.
7. Clear coat the area
Once the paint has dried, apply a clear coat to the area. This will help to protect the paint from damage and will give it a glossy finish. Allow the clear coat to dry according to the manufacturer’s instructions.
Tips
- If the rust hole is large, you may need to use a metal patch to repair it. These can be purchased at most auto parts stores.
- Be sure to wear gloves and eye protection when working with rust and chemicals.
- Allow plenty of time for each step of the repair process. This will ensure that the repair is done correctly and will last for years to come.
