Tinted windshield judging

Re: Tinted windshield judging

I would appreciate someone who knows what they are looking at comment on the tinting across the windshield and the transition. I don't really know what to look for as to correctness and whether this later replacement glass was still configured as the original 66 tinting.

Thanks[/QUOTE]

Don .

I am no expert , but as I understand it , the tint line is somewhat arched on original windshields .That is it is narrowest in the center and lowest on each out side edge.

Your pictured replacement seems to suffer the same malady the new repops have, that straight across line.

This is the original tinted windshield in my 65.

Re: Tinted windshield judging

... I know that Auto City Classic get their glass from Thailand as I just saw a 67 installed windshield that still had the manufactureres sticker on it, and it was a Thai company.

I though I read somewhere that Pilkington glass is produced in Mexico. I have not called them, but when I look on the Pilkington Classic website it says they are out of stock for windshields. I'll give them a call next week.

I would however like to know why you suggest Pilkington. Have you used them, or have good first hand knowledge? ...

Nippon Sheet Glass is one of the four largest glass companies in the world and Pilkington is their company for automotive sales. I expect their QA would reflect their market position. The other major players are: Asahi Glass, Saint-Gobain, and Guardian Industries.

Re: Tinted windshield judging

David, you just answered some more of my questions. Pictures below are the LOGO/Date of the windshield I removed. It is what I beleive to be an OEM replacements with UG dating, so I assume it was July 77, or July 90 per the LOF dating scheme. I was considering reinstalling it since the standard deduct is 20% for incorrect dating versus 50% for the tinting. But with the DOT 15 also in the LOGO/Date I'm now wondering if ONLY standard deduct is applied, i.e. 20%. Or can a judge also apply CDCIF and hit me for CONFIGURATION due to the DOT 15?

OR, would I get a 30% deduct for a OEM brand, later service replacement style with correct tinting?

Also, the LOGO/Date on this later replacement reads from the outside versus inside as is stated in the TIM&JG. So possible more deduct under CDCIF!!

I would appreciate someone who knows what they are looking at comment on the tinting across the windshield and the transition. I don't really know what to look for as to correctness and whether this later replacement glass was still configured as the original 66 tinting.

Thanks

Don - Windshield & Door Glass are subject to Standard Deductions. CDCIF is applied only to those items / parts that have no Standard Deduction table.

Re: Tinted windshield judging

I have not seen a reproduction tint band that could pass judging. There are other characteristics of the color /fading of original glass that sets it apart. Original good glass is hard to find and it most likely will be in need of professional restoration. You will be looking at $2000-4000 if you are lucky. The point deduction makes it worth on a high dollar car.

Even original tint bands sometimes do not pass judging. I am the second owner who knew the first owner of a December '66 and have all records of repairs since purchase. I know for a fact it's the original windshield but received a 10 point deduct with the notation "AJ S/D tint line S/B gradual". AJ is a September 1965 windshield for a late December build and it has never been off the car. My friendly judge misread the chart and misjudged the tint band. I was too naive to argue. Still got TF so not worth protesting.

Hank,

So what about the current reproductions logo and date etchings. How is that judged? In post #8 above, Mark said that sometimes judges will deduct for the fonts. If the fonts and etching process is judged to be different than original does that fall in the 20% standard deduct. What is confusing is how the standard deducts read, none of them seem to address the configuration of the logo/date etching.

If I buy and install all new reproduction clear glass (since all of mine existing glass was replaced in the mid to late 70s per the dates of the glass), then is the most I could loose is 20% due to configuration of the logo/date etching since the standard deducts for 30%, 50% and 90% seem to be mostly concerned with tinting.

Thanks,

Re: Tinted windshield judging

Modern glass also has a "waffle" pattern to it that can be easily seen in the right light. If you wear polarized lenses, it really sticks out. So, you could therefore lose on configuration and/or date with modern glass even if you use clear.

Just an FYI.

Re: Tinted windshield judging

Don,

Glass is judged using Standard Deduction Guideline #4 - CDCIF is not used when a Standard Deduction Guideline covers the item.

OEM glass transferred from another Corvette dated within 12 months prior to assembly date would have no originality deduction.

OEM glass transferred from another Corvette dated outside the 12 month window would have 20% originality deduction.

OEM service replacement with correct tinting 30%.

OEM service replacement with incorrect tinting 50%.

90% originality deduction 53-62 with tinted front or side glass - or any year adding tint (film, etc) - or any non OEM brand replacement.

If your replacement glass is non OEM brand it would be subject to a 90% deduction. Adding a LOF logo, to a non OEM manufactured glass, does not make it OEM.

Re: Tinted windshield judging

... Windshield logo & date ... ... The CDCIF methodology, therefore, should NOT be used. If my car were being judged I would ask the team leader why and how both a standard deduction and a configuration deduction would apply on the same line item. I’m speaking to the process ... Hank

Hank,

Only the standard deduction applies in the glass judging process. The logo and date (as well as tint) are used to determine which standard deduction percentage applies. For example: If looking at the logo, the judge determines the glass is non OEM, then a 90% deduction applies.
NO CDCIF matrix evaluation - deduction is 90% - move on to the next item.

Other examples: looking at the logo, the judge determines OEM glass but date indicates outside the 12 month prior window, then a 20% deduction would apply. If looking at the logo, the judge determines OEM brand service replacement with incorrect tinting, then a 50% deduction would apply.

The judge does not calculate the percentage deduction via a CDCIF matrix evaluation.

Dave –

Agreed. That is exactly what I said in post #27.

Re: Tinted windshield judging

If your windshield is original and the judge blew that call, he needs to see an eye doctor. It's that obvious.

Re: Tinted windshield judging

So I've been told. This was at the Florida Regional inside the hangar so I'll blame it on poor lighting. That and a judgement that my original paint was clear coated (not true either) cost me a chance at Bowtie. At least I know what is really there and documents to prove it. The first owner kept a journal of every oil change, tire rotation, fan belt replacement and even a minor rear end accident. He would no doubt have noted a clear coat and windshield change... and I certainly didn't touch it!

Re: Tinted windshield judging

Hank,

My mistake. I thought you were asking why and how both a standard deduction and a configuration deduction would apply on the same line item. We agree, only the standard deduction applies - not both.
