"I like the product, but it takes multiple applications to work correctly!"
I purchased Cat Crap to use on sunglasses that would be worn with a balaclava. After the initial coat to the lenses, I put the sunglasses on. They began to fog and a second coat was necessary. The second coat worked well, and I had no problems for the rest of the day.

I purchased this product to use for sunglasses which were to be worn while wearing a balaclava. After applying Cat Crap to the lenses, I put on the glasses, but they still fogged. I applied a second coat, and had no problems. I would recommend multiple applications right from the start if your lenses have never been treated.
"Cat Crap on your sunglasses prevents fogging (the anti-fog, not the stuff in the litter box.)"
The design of my favorite pair of sunglasses doesn't allow for much ventilation. So, they were fog city in any sort of warm weather. I applied the Cat Crap anti-fog as instructed and it totally works! I've worn the sunglasses on a few warm and sunny days, running and walking my dog and absolutely no fog whatsoever. I'm looking forward to seeing how it works on my vaca to hot, steamy Belize next month.
