For really stubborn, thick ice, Prestone also makes a de-icer product in an aerosol can with a built in ice scraper. "It's a great alternative to early morning scraping for seasonal frost, and in the dead of winter, a great product to have in the trunk to help clear your windshield after an ice storm". said Megan Currie, Prestone product manager.
These products are available at Canadian Tire and Loblaws Company of stores. More information on how to prep your vehicle for winter is available online at www.Prestone.com.
