I love my new 2008 HCH, but....I live in rainy Oregon, and every day have to either see behind me through a blur, or use a squeegee on the rear window to get off the beaded-up rain. Due to the slope of the window, driving speeds, at least in town, don't do much to get the water off. I miss the windshield wiper I have on my Volvo station wagon.
I've considered using Rain-X, but had a bad experience with it on my VW Rabbit back in 1982 or so, as it seemed to actually increase the problem of beading up of rain except on surfaces that got a lot of wind force blowing off the rain.
Anyone have any experience with Rain-X on this particular model's rear window?
On a bit of a tangent...I've read the other posts about Rain-X Fog-X or whatever it's called for the inside of windows. I hate

having to run the defogger essentially every day due to the high humidity, seems a real waste of fuel. Any other people in rainy climes having success or failure with such products?
