The ES 350 brochure notes that only the front side door glass is water repellant. However, I noticed after claying the windsheild that rain seems to roll off the windshield somewhat similar to the front side windows when it rains. The glass appears to have some sort of water repellant properties to it, though not as effective as the front side windows. Anyone knows if this glass is supposed to be water repellant?

 

I believe only the front side windows have some sort of water repellency.

I usually put on a layer of Rain-X on the front and back windshields and it's good for about 1-2 months depending on how much rain you get. It beads the water quite well.

 

Yes, it's only the front side windows.

 

+1 on the Rain-X. Love it.

 

I believe it is only the front side windows. What you are seeing with your windshield is the water repellent benefit of really clean glass due to your claying. I've noticed this as well - the clay gets everything off the glass and water slides right off just like it does on a new windshield. Somewhat of a similar effect on clean paint after claying.

I noticed the automatic wiper sensor doesn't like Rain-X over it. Try to avoid it during application.

Only the front door windows have water repellant on them from the factory. Why not the other windows I'll never know.

 

Yes, and the wipers seem to operate smoother and wipe much better as well. I think I will try to clay more often.

 

Guys -- lay off the Rain-X! It's silicone based, which evetually transfers itself to the wipers, effectively "sealing" the rubber -- which will cause premature drying and rotting.

Look into Auqapel, which is made by PPG. Not only does it not raise h*ll with the wipers, it also lasts upwards of six months per application.

 

interesting, I did not know that.

Does the aquapel also leave a bit of a haze on the windshield if not completely buffed out?

I''ll give a shot and see. Thanks for the tip.

 

cool, thanks for the heads up on that product !

 

I haven't noticed any haze after buffing it off -- perhaps I'm too thorough?!

For those having any difficulty finding the product -- I purchased mine from Amazon last year:

http://www.amazon.com/Aquapel-Automo.../dp/B001VGFJFI

It *was* about $16 for the 4 applications (and was Prime shipping eligible) at the time. I'm sure it's available at some B&M stores, I just haven't come across it.

Also, the applicator is generally good for only one windshield. I was able to squeeze out enough to do two once. However, if it's hot and dry out, you'll find that it evaporates pretty quickly...
