Car rust can cause major body damage that can be costly to repair. The older your car gets, the more at risk it becomes for rust. If rust affects your vehicle, it can serious depreciate the value and make it difficult to resell. To stop rust, periodically check your vehicle for the early signs of rust damage.
Look at areas of your car's body that are most prone to rust damage. These include the wheel wells, the fenders and the front end. Since rust is often caused by chips in the paint and nicks that occur from road debris, these areas are most susceptible.
Use automobile paint to touch up any chips you come across after examining your vehicle. Chips can worsen and lead to rust if not covered quickly. If you don't have any matching paint handy, use clear nail polish.
Sand down any nicks with surface rust. Use 220-grit paper to get down to the bare metal. You can then use the auto paint to cover the gap that you have made.
Clean the undercarriage. Power-wash the wheel wells and the underside to get rid of any caked mud dirt. Dirt can hold in moisture and cause rust to appear.
Shampoo your rug. To stop rust from forming, take the time during the winter months to have your auto rugs shampooed. The moisture and salts transferred from your shoes can cause rust to form under the rugs if not cleaned properly.
