To help drivers that don't have the luxury of parking their vehicle in a garage during the cold weather months, Prestone Lab Technician Rebecca Marshall has literally spent the last four and a half years developing and testing Prestone Ice & Frost Shield Vehicle Glass Treatment, often in temperatures well below freezing. "We put it to work outdoors against the cruelest conditions with comprehensive field testing over several New England winters," said Marshall. "Since I never knew what Mother Nature would bring, I applied the product almost every night." Otherwise known as "The Night Before Frost Blocker," Ice & Frost Shield is a concentrated high-performance formula that provides a resilient barrier between the environment and automotive glass, thus reducing the formation of frost, and the adhesion of frost, light ice and snow on vehicle windshields and side windows.
