Removing Rust from Your Car

Rust is the enemy of any car, large or small. It can form on any weak spots and weaken the structure of a car, as well as create unsightly spots. Fortunately, it is possible to remove rust from your car if you apply the proper techniques and products.

What You Need

  • Sandpaper in multiple grits (150, 300, 600)
  • Water
  • Scouring pad (optional)
  • Rag
  • Rust Reformer such as Por15 (optional)
  • Primer & Paint (optional)


  1. Begin by wet-sanding the affected area with 150-grit sandpaper. Sandpaper with a coarser grit will take away the rust, but it will also leave scratch marks. Therefore, start off with the lowest grit and work your way up.
  2. Wet the area with water as you sand. This ensures that the metal surface does not heat up and that no dust remains to cover the area.
  3. Once the rust has been removed, switch to 300-grit sandpaper. If the area is very rusty, you may want to start with a scouring pad first. Use the same wet-sanding technique as before.
  4. Rinse the area again with water and then switch to a 600-grit sandpaper.
  5. Once all the rust is gone, rinse again with water and dry the area with a rag. The sanding process should have created a rough surface, so use the rag to smooth it out.
  6. (Optional) For areas with exposed metal, you may want to use a rust reformer such as Por-15. This product will prevent new rust from forming and will also give the area a protective coating.
  7. (Optional) If the area is still visible, you may want to use a primer and paint it to match the rest of the car.

By following these steps, you should be able to remove rust from your car with relative ease. Prevention is always better than a cure, so make sure to wax your car regularly to protect the paint and prevent rust from forming.
