Ooo i'm curious to know this too! I'm guessing about 30LBS at least...

 

Thanks guys. Not everyone will want to tackle this job themselves, there is a lot that can go wrong, but if you just take your time, you will be a lot more careful than someone else with your own car.

I find factory glass better even beyond the special coatings and whatnot. Aftermarket glass usually has from slight to considerable distortion when viewed at an angle, OEM usually has none. Factory glass also seems to crack less easily from what I've seen in the past. In fact this was the first crack I've had in a windshield, I've had multiple chips, but I usually get them repaired right away. This was a BIG chip and I think it must have been from someone driving by my parked car or something, I don't know. I don't remember it happening while I was driving and I noticed a couple of chips in weird places on my fenders beside the windshield as well. They've been paving my streets lately, maybe it was one of their trucks? Not sure. Still I definitely prefer factory glass, though it definitely does come at a premium.

Honestly I didn't really pay much attention to it, but it's probably around 30-35lbs.

Again, you just need to go slow and take the time to read the manual on how to do things. When people get impatient things get damaged. Replace broken clips and be careful. Find out how things come apart before trying to take them apart. These are my mottos, lol.

I took a picture of the foam so you can see what it is:

Well the job is all done now, drove the car home tonight, here are my final pictures of the install:

JDM tyte!


So after opening up the new factory glass, I found that the new glass had the factory-style 1-piece stopper clips already installed on the glass. The ones I previously posted (2-piece), are to be used when reusing the glass I guess, or if you wanted to use them on aftermarket glass I guess you could. You can see the markings on the glass for positioning the stoppers.


The first step to prep the glass is to apply glass primer to all of the areas where adhesive is going to be applied, this includes where the upper moulding and adhesive dam go. After applying the primer and letting it dry for 3 minutes, I installed the upper moulding and adhesive dam to the glass, making sure to take careful measurements so it all went in the right place.


I then test fit the glass in the car to make sure it was correct, the factory upper stoppers worked beautifully to position the glass, and after a slight adjustment to the right it was sitting perfect.


After the successful test fit, I cut the tip for the urethane to a V-shape as per Lexus' instructions. Using a V-shape actually makes it easier to apply an even bead as well I've found versus using a round bead. V-shape: 8mm x 12mm high, though it actually ends up being about 6-7mm wide as you go, which is on par Lexus' instructions stating a 3mm centre-line for the V.


You can see that once the glass is in place, there is almost no excess. The upper stoppers again held the glass in place and I had marks for left/right position so that it would also be perfect. Here you can see the side area and the perfect amount of urethane without any excess to bond to the side moulding, etc.


Here you can see the glass installed with the new blue side moulding clips installed on each side. These are to be removed/replaced when changing the windshield. They are basically 1-time use clips and I had to replace them all.


Finally after waiting the prescribed 5-hours for curing, the car was ready to drive. New windshield installed, all interior put back in, no excess urethane, nothing scratched or cut. I didn't even get any urethane on my hands (a first) while doing this installation. I am very pleased to say the least.

Just in-case Jeff didn't mention it. Since it is a Canadian car, his car does have the front windshield deicer so if one were to order the glass, get the right one!!

Jeff, in the photos, I don't really see the front windshield deicer in there. Can you take a better pic of them?

 

Nice detailed pictures.

Too bad I can't tell what's making that dashboard creaking problems that so many people here have. I stopped mine by stuffing a lot of foam in the crack between the dashboard and windshield.

 

Nice, glad it's all done and installed. Did you leave the "Made in Japan" sticker on there? I left mine on there after having it replaced

 

No, I took it off, lol.

Great work Jeff.

 

Congrats Jeff..!!

This is on my "to do list" once I decommission MY IS-F as a daily driver...

Seems like a LOT of effort for minimal (if any) benefit. But to each their own.

 

I guess so, but every time I've ever had someone else do an install, at least one of the steps has gotten botched one way or another. I end up with my headliner glued to my roof, or some dirty urethane fingerprint on my a-pillar trim, or a small cut on one of the a-pillar trim, or broken clips on the cowl, or wipers installed in the wrong place, or the glass sitting slightly too far to the left/right, or visible urethane inside the car, or the glass sitting too high, or the mouldings installed incorrectly with missing or broken clips, or the moulding just glued in place with no clips, or whatever else they forget to do, or whatever. (Every single thing in that list has happened to me personally on various cars, and I haven't had that many windshields done. Feelsbadman.)

Instead I just spent a day slowly prepping and working on my car, it wasn't stressful or even that hard, just takes a bit of time. I've seen how most glass installers work, both in person and watching "instructional" videos online, and quite frankly I don't want any of those people getting near my car. If someone was to cut my glass out again, they would have no idea it wasn't done at the factory. That's definitely worth it to me.

Most glass places will look after you if something goes wrong, like an A-pillar is scratched or if they cut something, but honestly I'd rather NOT have something happen than have somewhere that will look after me when something does go wrong (which it frequently does). We have windshields replaced daily and I've never seen one done what I would consider correctly.

To each their own indeed.

EDIT: What it comes down to, is that yes you can save hours of time if you skip steps to do things differently, but there are risks. I'm not one to take those risks. Most glass installers do 85% of the job in 10% (or less) of the time. For them, that makes sense, for my own car it doesn't.

I think Jeff needs a new title: Glass installer

 

I'd prefer not to have that title, haha. I do my own glass, not so much for other people.

Awesome post Jeff. Very useful info.

 

how about... Pro Installer!

amazing detailed work done!
