Covering a large hole in a car body is essential to prevent further damage from rust and water. There are a few different ways to do this, depending on the size and location of the hole.
One common method is to use a fiberglass repair kit. These kits come with everything you need to patch the hole, including fiberglass resin, cloth, and hardener. To use the kit, simply clean the area around the hole, apply the resin to the cloth, and then press the cloth over the hole. Allow the resin to cure, and then sand and paint the area.
