How to fix small rust spots on your car
1. Gather materials
Before tending to the repair area, gather these materials:
- A sponge
- Car wash detergent
- 50-grit sandpaper
- Rust inhibitor
- Automobile primer
- Car paint
2. Examine the rusting area
First, confirm that the rust damage is indeed minor. If the rust has eaten a hole (even a small one) through your car's exterior, there's a good chance it's also started to corrode the underlying structural components of your vehicle.
If the rust is more extensive than you anticipated, consider taking it to a professional so they can determine the extent of the damage and whether or not it constitutes a simple fix.
3. Wash
Use a sponge to clean the entire area with a mild detergent. Rinse with water and dry completely with a microfiber towel.
4. Sand
Apply painter's tape to frame the affected area. Use 50-grit sandpaper to sand off the rust (and paint) until the underlying bare metal is exposed. This step may require several strips of sandpaper.
5. Apply rust inhibitor
To prevent more rust from forming on your car's surface, spray the exposed metal surface with a rust inhibitor. Rust inhibitors can be found online or at your local hardware store. Once you’ve applied the rust inhibitor, let the area air dry.
6. Apply primer
Spray any brand of automobile-specific primer onto the affected area until it is evenly covered. Let it air dry for at least 30 minutes.
7. Apply paint
If you don’t know your vehicle's exact paint color, the paint color code is usually located inside the glove box on the driver’s side door jamb under the driver’s seat or under the hood. Once you've determined your car's color, you can order paint online or through your vehicle's manufacturer.
Spray the base coat on the repair area and then let it air dry for about an hour. Apply additional coats as-needed.
8. Apply the clear coat
Spray the clear coat around the area and let it air dry until the surface is shiny and smooth.
Remove the painter’s tape—and voila!
Your car’s surface should look sparkling clean, with no signs of surface rust. Remember, avoid
washing your car
for a week to let your new paint job cure.RECOMMENDED
