Prestone Radiator Stop Leak features a patented formula that quickly stops leaks in radiators, water pumps, and heater cores while also protecting against pitting and corrosion. Prestone Radiator Stop Leak takes sealing performance to a higher level by both stopping the leak as well as the corrosive condition that causes leaks in the first place. Its unique combination of natural and synthetic components provides the ability to seal leaks up to 0.020-inches x 0.5-inches. What makes this possible is the size, strength, and durability afforded by fibrous particles, the same materials in bulletproof vests. Prestone Radiator Stop Leak particles have been chosen to seal even large leaks without interfering with the flow through the radiator and heater core tubes. It also boosts corrosion inhibitors to protect against pitting and corrosion, which cause radiator leaks.

Ice and 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!
