I've also wondered how to get rid of those problem drops. I think the main culprit, though, is any film of water on the lens. I'm pretty sure RainX will minimize this. The film of water will distort light and can't really be brushed off. RainX does allow drops of water to bead, but by forming a protective layer on the lens so that the drops don't collect and linger long enough to coat the lens. I will try this today. RainX directions say to use two applications of the product. I know that when I use it on my windshield, I don't even have to use wipers. Just driving around will force the droplets to run off the windshield, so I'm thinking that a couple of good shakes of the housing or blowing on the lens will remove enough of the drops to take a decent pic.
