HAS ANYONE NOTICED MORE ROCK CHIPS IN WINDSHIELDS AFTER INSTALLING A BRUSH GUARD ON THEIR PICKUPS? I BELIEVE THE TOP BAR DISRUPTS THE UPWARD FLOW OVER THE HOOD. I HAVETWO TRUCKS , THE ONE WITH HAS HAD 6 CHIPS IN THE LAST 3 MOS AND THE ONE WITHOUT , BUT WITH A BUG DEFLECTOR HAS NONE IN 5 YEARS , SAME ROADS TRAVELED AND SAME SPEEDS.
