How to Fill Bolt Holes in Car Body

Introduction

If you’ve ever had to remove a bolt from your car body, you may have noticed that it left behind a small hole. These holes can be unsightly and can even allow water and debris to enter the vehicle. If you want to fill these holes and restore your car’s appearance, there are a few simple steps you can follow.

Materials You’ll Need

Before you begin, you’ll need to gather a few materials:

* Body filler
* Putty knife or spreader
* Sandpaper
* Primer
* Paint

Step 1: Clean the Hole

Start by cleaning the hole with a damp cloth and rubbing alcohol. This will help to remove any dirt or debris that may interfere with the adhesion of the body filler.

Step 2: Apply the Body Filler

Once the hole is clean, apply the body filler to the hole using a putty knife or spreader. Fill the hole completely and smooth the surface of the filler.

Step 3: Sand the Filler

After the body filler has dried, sand it down until it is flush with the surrounding surface. Use a fine-grit sandpaper to avoid scratching the surface of the car.

Step 4: Apply Primer

Once the filler is sanded, apply a coat of primer to the area. This will help to seal the filler and prevent it from absorbing water, which can cause rust.

Step 5: Paint the Area

Once the primer has dried, you can paint the area to match the rest of the car. Be sure to use a paint that is designed for automotive use and follow the manufacturer’s instructions.

Additional Tips

* If the hole is large, you may need to use a backing plate to support the body filler.
* If the hole is in a difficult-to-reach area, you can use a flexible putty knife or a brush to apply the body filler.
* Be sure to clean the putty knife or spreader after each use to prevent the body filler from drying out.
* If you are not confident in your ability to do this repair yourself, you can take it to a auto body shop.

Conclusion

Filling bolt holes in car body is a simple repair that can be done in a few easy steps. By following these instructions, you can restore your car’s appearance and prevent rust.
