“The Night Before” Frost Blocker :
Ice & Frost Shield Vehicle Glass Treatment dramatically reduces the time, effort and hassle it takes to clear your winter window glass. Simply spray on when you park your vehicle (for the evening) and wake up to the faster, warmer, friendlier way to start your day. The alternative to scraping means that morning frost, light ice and heavy snow won’t stick and you may never need to scrape again!
Ice & Frost Shield Vehicle Glass Treatment is a robust formula that provides a resilient barrier between the environment and automotive glass, thus reducing the accumulation and adhesion of frost and light ice. The copolymer active ingredient imparts a balance of hydrophobic and hydrophilic characteristics, which provides durable protection without compromising visibility. The formula was developed and rigorously tested in the Prestone Research and Development laboratory in an environmental test chamber. Its performance has been confirmed in a comprehensive vehicle fleet test enduring a New England winter. Prestone® Ice & Frost Shield Vehicle Glass Treatment can be used on a daily basis without altering your vehicles windshield.
