Covercraft MH Series Deflectors for cars. At the top of the hood curve, Covercraft has added a reinforced bug deflector that creates a swirling wind action to divert most bugs, dirt and debris away from the windshield. Unlike hard plastic bug deflectors, the Covercraft Deflector-Protector Mask can be removed in minutes and stored in the trunk. There are no holes to drill or hardware to attach as it installs quickly and easily using an envelope design and tightening strap under the hood to hold it securely in place.
