Are front windows treated with anything?
Got lazy over the weekend and ran the RX thru the toucheless wash..I.noticed that as the soap and water was being sprayed, almost immedotaly did it bead off the windshield and 2 front windows..but not the rears. Just curious if anyone knows how this is? Its quite awesome its like rainx that I never applied!

Yes, the front side windows are treated.

WATER-REPELLENT FRONT DOOR GLASS
This feature has been around for the better part of a decade, and in current models it’s found on the front driver and passenger windows. “It’s a titanium-silica coating on the glass that helps make water bead up and run off, making it easier to see through the window and to see your mirrors when it’s raining,” says Charles Hubbard, senior dealer education administrator for Lexus College. “The effect is similar to what those aftermarket window treatments can do.”
The difference, of course, is that unlike some aftermarket products, this titanium-silica coating is permanent; it never needs to be reapplied, and it requires no special treatment. Just clean it as you would the rest of your glass.
Water-repellent glass is a subtle innovation, but one that’s easily appreciated by simply comparing the side-by-side behavior of water on the front and rear passenger windows; on the front, rain will bead up and roll off quickly, whereas on the rear, the water tends to sheet.
Incidentally, this is a reason to insist on genuine Lexus parts if you ever need a window replaced, as an aftermarket product likely won’t have this treatment.

"Water-repellant front-door glass" is cited as a standard safety item in the 2nd Gen RX Glossy Brochure, although I don't see it in mentioned in my 2013 3rd Gen brochure or in the online manuals after quite a bit of searching just now. To your point, though, I believe my 3rd Gen has a coating on just the front side windows to help improve visibility during inclement weather (no windshield wipers on the sides, right? 
). I've never read of a mfgr-applied coating to the windshield, so can't confirm your suspicion. In fact I apply Aquapel (IMHO lasts longer than RainX) to assist with sheeting action on my front and back windows.
