So these windshields have a film on them that De laminates over time.

Not even a coating. A vacuum deposition (sputtering) would be ten times better than a "tint" film laminated to glass.

You ever see sunglasses de laminate?

 

From owning one?

I can try to dig up some articles if you are really interested.

 

Keep in mind this was 18 years ago. Sunglasses don't tend to block radiant heat, which is what the film is for. The ZR-1's windshield was made by LOF, and appears to have some manufacturing defects. Other cars like the '91 "dustbuster" minivans had similar windshields made by PPG. They neither seem to cost a fortune, nor delaminate.

Feel free to keep replies here, I just didn't want to cut/paste the post

 

Something is wrong with that whole concept coupled with the fact that it is de laminating.

How would it de laminate if it were sandwiched in between Glass?

There are two ways to filter Photons through a lens.

One is you coat the actual lens
Two you put something else in front of the lens like a filter or poylmer membrane.

What you said was correct, that article that you posted did say that.

I don't question your explanation, I question the document that you got your info from.

I'm diggin' a little deeper today.

As a side bar, I make Photon filters everyday. My filters allow you to look directly at the sun and study the pools and solar rays......you give me a light wave and tell me what frequencies you want removed and we'll do it...

I can put a purple hue on glass, I'd just like a better explanation of what the General used when making these so I can offer up a similar item....seems this is a huge issue for the Z guys.

I can print a date code, I can mask an area........it won't cost you $2700 that is for sure

My point is this, If I can duplicate what GM did it would work for the NCRS guys....if I can't the rest of you can get a purple hue on your windshield for cheap.

Vacuum depositing material on glass is an a everyday occurrence, Most are limited by not having a chamber large enough to fit a C4 windshield inside to coat it....I have 10 chambers.....how many purple tinted windshields do you want.....this week?? how 'bout next?

 

I'm not sure what to say? If you've seen the final ZR-1 at the NCM, you could see the worst delamination ever. But it's between layers of glass. You can't remove the coating with a razor blade from either side, etc. How it can happen between the glass I can't explain, but it certainly happens.

If there's something you want me to test or check on mine, I'd be happy to (as long as it's non-destructive).

I suspect if you could make windshields that looked the same for cheap, you'd have plenty of buyers. If you started with an OEM C4 windshield, perhaps all the better. I suspect they are either LOF or PPG.

 

The windshields were specially made because of the HEAT given off from the ZR1 motors. You can't just coat the under side of a windshield and get people to pay $1000, plus.

 

I don't think too much motor heat makes it through the windshield. I believe the reason is the A/C compressor was smaller and thus they were concerned it might not be up to the task all that heat through all the glass. So the Koolof front and EZ-Kool side glass was used.

Though it's also possible they just wanted to try it out since it was new technology? I'd also sort of think most heat comes through that huge rear window. Maybe it just wasn't feasible to coat that? Or maybe it would look dorky with a purple rear window?

 

That's a good point. When I saw $2700 I literally laughed out loud. My kids start asking to see what was sooo funny.

Understand, my thinking is less than half that amount.

here is the deal, NCRS buyers may not be interested if they want to win the competition, but many others may be...and if you have to get a new windshield because of a rock chip or a large crack....well, wouldn't a Z windshield interest you for just a few bucks more??

And if I could see a Z windshield and we find that we can duplicate it exactly....I'll go for it.

Now, a bit of coating technology. Let's return to chamber size. The late 70s and mid 80s chambers weren't very big and coating technology was really pretty basic. We've learned tons in 30 years. Uniformity, surface prep, surface activation for the purpose of adhesion promotion......(this is the reason the originals are de laminating, poor adhesion)

So this is why I'm dabbling with this idea.

I like constructive criticism as I'd like to NOT get in deep with this and it turn out to be rejected for this or that.

So be constructive and ask questions that would make or break a deal for you, and I'll see if I have a solution to your question.

Thanks

 

I think you should do it, even a repro will get a point or two deducted, but so what. Many many more with ones they drive that I bet would snap them up if they were affordable and decent quality.
