One scope manufacturer's advertising states that its hydrophobic coating keeps the scope clear of water droplets even in the rain. This sounds much like commercial products such as Rain-X used for windshields etc. Has anyone ever tried using rain-x or something similar on their scopes or have any thoughts on the matter - eg: the possibility of rain-x damaging the other coatings on the scope. I've never used a scope in the rain (hardly ever used one at all) so I've no idea if rain on the lens really is, could be, a problem.
