Used this product on two occasions. Im in Tampa Florida where the humidity is 95-100%. I used it for an evening game with some Army Rangers and then all day on the next weekend. I NEVER experienced any fogging on my masks, while everyone else out there was fogging so bad and complaining about it. The product really does work.
Cleanup is easy with water.
Application was via a small pad, however, it was kinda difficult to apply inside the small mask with your fingers. Maybe a applicator bottle with a foam tip (kinda like liquid shoe polish) might be easier.....or single application wipes.
Once applied though.........no more fogging!
I would recommend this product. Its still in the testing stages for means of application, but I can verify the product does work as stated.
