How to Fix Pin Holes in Car Body
Introduction
Pin holes are small, rust-prone holes that can form in the body of a car. They are typically caused by corrosion, which is the result of exposure to moisture and oxygen. Pin holes can be a problem because they can allow water and other contaminants to enter the car, which can lead to further damage. If you notice pin holes in the body of your car, it is important to fix them as soon as possible to prevent further damage.
