I think you are right. It looks like laminated acoustic glass entered the Lexus line in 2006. I haven't found any information about coated glass on the windshield. I am mistaken.

 

Could be that this is the reason I didn't think much of the coated windshield feature. It isn't there!

 

Rain-X is the answer for those of who who think there is a special coating on Lexus OEM Windshield.

 

I spoke to the glass guy here, he says now(1year) PPG/PGW glass are made in China? Any one have opinion about the other American brand 'APT' (AP Tech)?

 

Here is an excerpt from another forum. I really don't know what the issue is here. The PGW glass is exactly like the OEM in every detail. I don't care at all if it is made in China.

I work at PGW and can offer an explination: These are NAGS stickers (National Auto Glass Specifications) aka, After-market. There was a joint venture between PPG and a Chinese company prior to the sale of the auto glass division which became PGW. While the Chinese are not making the OEM glass labeled as being PGW in North America, they ARE making some of the ARG (after-market) product.

Also, PGW has a plant in Mexico that makes windshields. (More can be found on the PGW website.)

You may be interested to know that on a few of next year’s car models, many of your “Big 3″ companies will be importing the glass from China. So, if you’d like to shed some light on outsourcing (especially when the American auto industry lives by the “buy American” mantra) take a look at where some of THAT glass is coming from. If it’s not PGW/Gaurdian/Pilkington/Owens-Corning, its probably not being made in the states at all.

Hope this helps explain. Thanks for taking interest in PGW, and our American jobs!

 

How long will silicon/glue takes to dry? Considering the road vibration, can I drive back (10 MIles) in 2 hours of installation? I am aware not to wash the car for next 2 days.

 

I had a windshield removed and replaced and shop kept car overnight to allow the adhesive to fully cure.

They use urethane, not silicone.

Here's a typical data sheet http://multimedia.3m.com/mws/mediawe...0-89-08566.pdf

Cure time s dependent on temp and humidity.

It's best not to rush.

When Safelite did mine a couple of months ago, I was told to park it overnight.

 

Based on the above link the cure time at 85 F (LA) is only few hours. Am I reading correct?

 

I can't answer that. I know the body shop had a mobile glass guy R&R my windshield and they insisted on having it overnight to fully cure. That was in 80 deg weather.

Several years ago I had another windshield replaced by in my driveway by a mobile glass shop. They also requested I not move it until the next morning.

Perhaps you could have a mobile guy come out to your house.
