  • Check door frames and hoods for signs of rust.
  • Inspect areas with potential rubbing points.

Donโ€™t allow water to sit in or on the vehicle.

Donโ€™t allow water to sit in or on the vehicle.
Your vehicle is designed to withstand most things regular weather can throw at it. Paint, clear coats and plastic trim pieces are all intended to protect the metal on your vehicle from rusting, but over time these forms of protection can become compromised. If you notice an area of your car or truck that tends to hold water.
  • Check for areas where water may collect.
  • Use a hose with a spray nozzle to rinse off any debris.
  • Avoid using high-pressure washes on the vehicle.
