Rifle Scopes using rain-ex

[223man]

I had read a post some time ago and can not find it. But it was said to use rain-ex on scope lens. Is this a good idea or not. The reason I'm asking is because I am going shooting this weekend and needless to say it is raining here in WA. So I want to know will that help with getting that fog and or "morning dew". I know this sounds like maybe a dumb question but as said before I'm a noob so be gentle.

I wouldn't do it, especially on high quality glass. Lenses are usually coated, and solvents will strip that coating off and undermine the work of the crafters.

Re: using rain-ex

your scope lens is coated, I wouldn't do it. Just get a sunshade to keep the rain out

That's what I was concerned with was damaging the coating so I wanted some opinions before I f'ed up something.

On the bottle it reads not to use on coated lenses. I called Leupold and asked them their recommendation and the service rep. said they recommend Klear-VU.
I don't like any of the anti-fogging agents myself, I've tried several. Cat crap gets smudgy, and the liquid ones seem never to offer the effect I'm looking for. Rainguard and the like have solved this equation from Bushnell and many others have followed suit.
I just usually carry a lense cloth with me when hunting.

I just blow it off and hope a target doesn't appear until the fog on the lense dissipates.

I have some stuff that I got from the ILEA courses, but I have not tried it yet. I wanted to run it by USO before I smear it on my lenses.

or you can try weaver see thru polar caps. they are polarized / coated, you can wipe em off without worrying about scratching your glass, then pop em open if you need to shoot dry.

Rain-x is designed for harsher road environments, not the crisp lens of a scope. As long as they make camera lens cleaner and lens pens, I would use those instead.

Parkers Perfect is a anti fog, but it does have some qualities that Rain-X does. Give it a try, it won't damage your lenses.

When the eyepiece fogs over, reach up and give it a good lick with your tongue, it works better than anything else I've tried, and you've usually got it with you.

The objective usually won't fog, just get raindrops on it, and you can usually shoot through those. A lens shade or killflash will help keep some off, but will reduce your light input.

Parkers Perfect spotted up my lenses terribly, but if anyone wants to try some, PM me and I'll send you some to try out. I think you will be disappointed.
