Neverfrost is a Waterloo, Ontario based nanotechnology startup specializing in durable, transparent, anti-frost coatings.
Neverfrost is a film that you apply one your car's windows and windshields. It's completely transparent so that drivers are safe on the road, and one application prevents frost for 3-5 years. To top it off, the surface of the film is also treated so that snow and ice do not stick to it. Neverfrost films are also resistant to scratches and stone-chips. This means you'll be safer on the road when the odd stone comes flying at your windshield and leaves you with a $500 bill to get it replaced - there will be no more of that either.
Here's the best part. While Neverfrost prevents frost & keeps your car warm in the winter, it also prevents your car from heating up in the summer. This means you'll no longer have to worry about finding a parking spot in the shade or getting cooked in your car when you come back in case you had to park in the sunlight.
