How to Fill Screw Holes in Car Body

Step 1: Gather your materials

You will need the following materials:

* A drill
* A countersink bit
* A screw
* A screw cap
* Car body filler
* A putty knife
* Sandpaper
* A primer
* Paint

Step 2: Drill a pilot hole

The first step is to drill a pilot hole for the screw. The pilot hole should be slightly smaller than the screw. This will help to prevent the screw from splitting the wood when you insert it.

Step 3: Countersink the hole

Once you have drilled the pilot hole, you need to countersink the hole. This will create a slight depression around the hole so that the screw cap will sit flush with the surface of the wood.

Step 4: Insert the screw and screw cap

Now you can insert the screw into the hole. Be sure to tighten the screw securely, but do not overtighten it. Once the screw is in place, you can screw on the screw cap.

Step 5: Fill the hole with car body filler

The next step is to fill the hole with car body filler. Apply the filler to the hole using a putty knife. Be sure to fill the hole completely and smooth the filler out around the edges.

Step 6: Sand the filler

Once the filler has dried, you need to sand it down so that it is flush with the surface of the wood. Start with a coarse sandpaper and gradually work your way up to a fine sandpaper.

Step 7: Prime and paint the area

The final step is to prime and paint the area around the hole. This will help to protect the wood and make the repair less noticeable.

Tips

* If the hole is large, you may need to use a washer or backer plate behind the screw to prevent it from pulling through the wood.
* If the screw is rusted, you can use a penetrating oil to loosen it.
* If you are not confident in your ability to fill the hole yourself, you can consult with a professional auto body repair shop.

Conclusion

Filling screw holes in a car body is a simple repair that can be done at home with a few basic tools and materials. By following the steps above, you can make the repair virtually invisible.
