A well-designed bug deflector hood shield protects your vehicle in two ways: first, it shields the leading edge of your hood and fenders from stones and other debris borne by the wind or thrown up by other vehicles, keeping your hood and fenders free of dings, dents and chipped paint. Second, the lip of the shield redirects airflow enough to propel bugs and debris up and over your vehicle, instead of crashing and splattering into your windshield, preserving and maintaining your visibility and keeping your windshield free of chips and scratches. The Bugflector II Hood Shield is one of the best-selling automotive products in North America because it's so effective at both tasks.
