After a few rainstorms our domes are covered with waterspots. Cleaning the domes is a PITA because we need a knuckle boom to reach most of the exterior cameras. I've been thinking of using some Rainex or something on the domes to minimize maintenance. What do you guys use to keep your domes clean?

You know, I've always wondered how to keep it clean when I was working retail security. Nothing pisses you off more than trying to zoom in to get a license plate... only to see a distortion. I'd think the rainex would be a great idea. Let us know how it works.

ya know i have thought about using rainex before but have been to afraid.
One time with my car I did not fully clean my windshield before putting rainx on it and regretted it for about 3 months.

2 different manufacturers have told to me to use Rain-X. They said one application a year would be neccessary.
