Waxing Lexus 460 windshield - water smearing

[LKimura]

My friend has a new 460. The window is not water repellent as advertised. When he drives in the rain the water "smears" so bad that he cannot see. He has to pull off of the road. It is worse with the wipers on because the water smears rather than being wiped off. The dealer has changed the windshield and the 2nd windshield does the same thing.

Now the dealer is going to wax the windshield which is suppose to fix the problem!

Isn't this going to make it worse?

Won't it eventually "wear" off?

Does anyone have any idea why this is happening? Does the Lexus come with some type of dressing on the windshield from the factory? There was a "scratch" on the windsheld which I think was on some type of coating rather than on the glass.

thanks for your help and ideas.

Depends on what kind of wax they use. I put Klasse All In One on my glass last fall and it was still beading water before I reapplied it the other day, albeit not nearly as well. I'd imagine you could get away with 6 months per app so twice a year wouldn't be bad to wax/seal some glass?

My case is dealing with just normal glass. Maybe see what this wax they use does and if it is worse, I would be inquiring as to how you could just get a normal bloody windshield, pick up some product and do it yourself.

I have a Lexus ls460. I don't have problems with the water smearing the glass though. From my prior Lexus, I have learned not to apply anything to the windshield and the front door glass because of the built-in water repellent glass. When I applied a glass sealant on my prior Lexus, the glass sealant would just smear and would not come off the glass...it was like smearing butter all over your windows.

Your friend's ls460 is definitely not normal. He should bring it back to a different Lexus dealership and get this fixed.
