I'm not that worried about the sand-based aspect. Does sound sketchy ya. But if this is a mass production glass protector cream, and it scratched glass, well they won't be in business long. Certainly wouldn't have the funds for ads on TSN (ESPN). So my guess it's a question of if it's more or less effective than the Rain-x original, and how long it lasts. I haven't tried either yet.
I want to try the Rain-x original product first since it's under $10. Then, if I feel glass treatment is the way to go, I may move up to the sand stuff Itekt.
I feel like foggy windows in my Mirage in bad weather has to be improved somehow. And I don't think I have any problems with my heater, I keep the car cleaned off well even though my Mirage parks outdoors all the time except at the mall.
