How to Paint Under Car Body
Materials You’ll Need
- Automotive paint (choose a color that matches the rest of your car)
- Primer
- Sandpaper (various grits)
- Body filler
- Masking tape
- Plastic drop cloths
- Spray gun or paint brush
- Clear coat
Step-by-Step Instructions
1. Prepare the surface
Begin by cleaning the underbody of your car thoroughly with soap and water. Once it’s clean, sand the surface with a coarse grit sandpaper to remove any rust or old paint. If there are any dents or scratches, fill them in with body filler and sand them smooth.
2. Apply primer
Once the surface is prepared, apply a coat of primer to help the paint adhere better. Let the primer dry completely before proceeding.
3. Paint the underbody
Now it’s time to apply the paint. Use a spray gun or paint brush to apply several thin coats of paint, allowing each coat to dry completely before applying the next. If you’re using a spray gun, be sure to wear a respirator to protect yourself from the fumes.
4. Apply clear coat
Once the paint is dry, apply a few coats of clear coat to protect it from the elements and give it a glossy shine. Allow the clear coat to dry completely before driving your car.
Tips
- Make sure to wear gloves and eye protection when working with automotive paint.
- Work in a well-ventilated area.
- Allow each coat of paint to dry completely before applying the next.
- If you’re not comfortable painting the underbody of your car yourself, you can take it to a professional body shop.

Painting the underbody of your car is a great way to improve its appearance and protect it from the elements. By following the steps in this guide, you can achieve a professional-looking finish that will last for years to come.
