Yes the Rain-X does work very well ,I use it on all my vehicles 1999 Dodge caravan , 2003 Toyota Prius currently and a number of others in the past and CCKW when the rain hits the glass the rain forms much smaller droplets on contact with a treated surface be it windshield or sidewindow or rear window , as a result you look thru a fine mist of droplets as anything larger runs right off and you don't have any film of water to look thru or to drag behind the wiper blades a real plus on the flat windshield of the CCKW as the wipers don't cover a lot of the area and the wipers don't work on those long hills unless you want to loose any speed by taking your foot off the gas to "see" where your going lol . True if you use the wipers it will take off the coating a bit faster but you reapply it every few months anyhow , I buy it in liquid form you can get it in a pump spray or towelettes .
