There are a few things you can do to fix bullet holes in cars. The first is to clean the area where the hole was made. This will remove any dirt and debris that may have been inside the car and may also help to fix the hole. Next, you should replace any parts that were damaged by the bullet. This might include the windshield, door panels, or other parts of the car. Finally, you should drive the car around until you see any signs of damage from the bullet. If there are no signs of damage, then you can finally drive your car back to its original condition by taking it to a mechanic and having it fixed.
