How to Repair Rust on Car Body
Rust is a common problem for cars, especially in areas with high humidity or frequent rain. Rust can damage the paint and body of your car, and if left untreated, it can eventually lead to more serious problems. Fortunately, rust repair is a relatively easy and inexpensive process that you can do yourself with a few simple tools.
Materials You’ll Need
- Rust remover
- Sandpaper (various grits)
- Primer
- Paint
- Clear coat
- Masking tape
- Gloves
- Safety glasses
Step-by-Step Instructions
1. Prepare the Area
The first step is to prepare the area around the rust spot. Use masking tape to protect the surrounding paint from damage. Then, use sandpaper to remove any loose rust or paint from the spot.
2. Apply Rust Remover
Once the area is prepared, apply a rust remover to the spot. Rust removers are available at most auto parts stores. Allow the rust remover to sit for the amount of time specified on the package. The rust should start to turn black or brown as it reacts with the remover.
3. Scrub the Rust
Once the rust has reacted with the rust remover, use a scrub brush to remove it from the spot. Scrub until the metal is clean and smooth.
4. Sand the Area
Once the rust has been removed, use sandpaper to smooth out the area. Start with a coarse grit sandpaper and gradually move to a finer grit until the area is smooth and even.
5. Prime the Area
Once the area has been sanded, apply a primer to the spot. Primer helps to protect the metal from rust and creates a smooth surface for the paint.
6. Paint the Area
Once the primer has dried, apply paint to the spot. Use a brush or spray paint to apply the paint evenly. Allow the paint to dry completely.
7. Clear Coat the Area
Once the paint has dried, apply a clear coat to the spot. Clear coat helps to protect the paint and gives it a glossy finish.
8. Remove the Masking Tape
Once the clear coat has dried, remove the masking tape. Your rust repair is now complete.
Tips
- If the rust spot is large or deep, you may need to use a body filler to fill it in.
- Be sure to wear gloves and safety glasses when working with rust remover and paint.
- Allow ample time for each step of the process to dry completely before moving on.
- If you’re not comfortable performing rust repair yourself, you can take your car to a body shop for professional repair.
