What is rustproofing?
Rustproofing protects your car from rust buildup using a variety of chemicals that form a protective layer. It targets specific areas where rust is most common, such as the fenders, tailgate, and upper body panels.
Rustproofing is usually renewed every one to three years and can take several hours to complete. The climate you live in and your driving habits can also influence how often you need to rustproof. Spring or summer is the best time to rustproof your vehicle, when the weather is warm and dry.
The steps to rustproof any vehicle are fairly similar, but some vehicles are more suited to the process than others.
Should you rustproof your EV?
Some manufacturers discourage rustproofing an EV (or hybrid) because it can weaken or void the warranty. It’s possible that the chemicals used in the rustproofing process can damage high-voltage electrical wiring if coated over certain parts of the vehicle, which puts the warranty at risk.
This warning also applies to undercoating. Undercoating is a type of rustproofing, but it focuses on the undercarriage of your vehicle, applying a barrier to fight against dirt, grime, and salt, which can lead to rust.
With a brand-new EV, rustproofing or undercoating isn’t necessary because the steel used to make the vehicle is typically treated in the factory (i.e., already rustproofed), making the material more resistant to corrosion.
When in doubt, refer to your owner’s manual and any other advice from your vehicle manufacturer.
Cost to rustproof
If you determine your EV is eligible for rustproofing, it’s wise to get it done professionally. Although some people DIY their rustproofing, leaving this task to those with verified experience is a better way to guarantee your protection against rust.
EV rustproofing at a dealership or garage can range from $500 to $1,000. You can request quotes from multiple locations before committing to an appointment.

Other ways to prevent rust
Aside from rustproofing, you can protect your EV from excessive rust by:
- Washing your car every two to four weeks, especially during the winter (don’t forget the undercarriage).
- Always parking under shelter/using a car cover to keep your vehicle dry.
- Repairing stone chips and dents immediately.
