How to Paint a Cars Undercarriage


Attention to detail is word one with show car owners. They polish and paint every single screw, nut and bolt. The reward for their hard work and patience is a trophy, or better yet, the coveted title of “Best in Show.” Is there anything that can be learned from these enthusiasts that we can apply to our daily driven vehicles? Yes. To prevent rust and to help your vehicle last longer, consider painting your vehicle's undercarriage. This will help to prevent your car from prematurely rusting away and might even aid in collecting a few more dollars at trade-in time.

Things You'll Need

  • Jack
  • Jack stand
  • Safety glasses
  • Water hose (with water)
  • Wire brush
  • Chassis paint
  • Air gun or brush
  • Air compressor
  • Park your car on a hard flat surface and apply the parking brake.

  • Jack up the vehicle. Place a jack under the vehicle and raise it high enough to allow you to work under the car. Rest the vehicle on jack stands. Do this to all four corners if painting the entire undercarriage.

  • Wash the car. Put on safety glasses. Wash the entire undercarriage of the vehicle with a hose and water and allow to dry.

  • Prep the vehicle's undercarriage. Using a wire brush, remove all loose paint, rust and road grime. Brush the entire undercarriage to aid in paint adhesion.

  • Rewash the vehicle. Spray the entire undercarriage again with water and allow it to dry thoroughly.

  • Paint the undercarriage. Using a chassis paint in a well-ventilated area, paint the chassis and undercarriage with either an air gun or a paint brush. Apply paint per the manufacturer's instructions and coat recommendations. Ensure that there is a good coat of paint on the entire undercarriage. Allow coats to dry according to the manufacturer's directions.

  • Raise the car up off of the jack stands using the jack. Remove the jack stands, lower the vehicle and remove the jack. Remove your safety glasses.

Tips & Warnings

  • Parking your vehicle over the top of a yard sprinkler overnight is a good way to get the salt and grime out of the hard-to-reach places of your undercarriage.
  • Using a rust preventative paint is best.
  • Never work under a poorly supported vehicle.
