Rain-X to reduce fogging?

[ninepointer]

Does anybody here use Rain-X on their scopes? How well does it work? Will it damage coated lens?

Never used it on rifle scope... but I did use it on binoculars, it didn't do anything in regards to fogging, but it did keep the occulars free of water.

Have not tried it myself, but I do remember someone mentioning to me that they did that.

I don't recommend this on a rifle scope but:
For hockey you can use the expensive defoggers on your visor, or use liquid dish soap. Let it dry and then buff it clear. It'll last one game max. Very inexpensive and worked decently.

Again I wouldn't use this on a rifle scope. I'm not sure what it would do to the coatings. It could ruin your scope.

I don't believe Rain-X is going to help fogging on your scope. Furthermore, it may not be compatible with the coating on the lens.

Buy a Bushnell with RainGuard is the more effective way to go.

I did it once on a low end Bushnell 3x9x40. Used it for one season and it was OK.

I was somewhat worried about damaging the coatings as well. I wouldn't do it with an expensive scope though, just to be certain.

After re-reading the question, I have to add to my answer that the guy who I heard was using it, was using it not for fogging, but for rain, like the Bushnell Rainguard does.
