72 Ontario Orange paint question

Re: 72 Ontario Orange paint question

Owen
In reality the computer color match system do not exactly match original paint.

Terry,
I didn't mean to imply that a computer could duplicate the original color(s), just that a digital color analyzer would likely show significant tonal variations between every sample amongst a collection of similarly colored vehicles. I would argue that there is no single tone/shade that could be the standard of any paint since even out-the-door factory paint varied.

It's all pretty much academic, but the devil lies in how close is close enough to represent the color.

Agreed, but that one word answer is too short for this computer system

Terry,
We appreciate you taking the time to respond to our Ontario Orange paint post. My son and have enjoyed our 72 LT1 renovation project, and will participate in future NCRS judging events when time / distant permits.

We agree with you that it is very difficult to try to duplicate 72 Fire Mist Ontario Orange paint. Hopefully we do have the opportunity to compare our to an . I would believe after 50 years a 72 survivor with original paint is somewhat rare?

Re: 72 Ontario Orange paint question

OK, FYI we recieved a judging deduction (#1 on the ncrs exterior sheet re: Body Paint originality) for "metallic content NTP (standard deduction 70%) ?

Hi Fred,

I'm curious...did the judge indicate what it was about your "metallic content" that caused it to be judged NTFP?

1. too much flake?
2. NTFP flake size?
3. not enough flake?
4. NTFP flake orientation?

Re: 72 Ontario Orange paint question

1. too much flake. The Exterior judge compared our paint to a ontario Orange paint chip (1972 Chevrolet Corvette 72 Paint Chip from Ditzler)

We discussed our position and challeged his interpretaion, without sucess.

Chapter event?

Pat,
The difference between the 1971 model year plaque (3/26/70) and the 1972 model year plaque (4/16/71) is the amount of metallic and the gold pixels used in the formulation. Back in the day, "slight" formulation variances in carryover colors was not uncommon.

Re: 72 Ontario Orange paint question

Terry,
Sounds like a pretty good idea and possibly include discussions on GMs master color plaque review and approval process.
FYI, my "71 LT1 coupe's birthday was January 20th, 1971, which is still in winter hibernation.
It's been a while since I did a plaque comparison. Next time I'm at the shop I'll have to take a look.

Re: 72 Ontario Orange paint question

Fred, I have enjoyed the photos of your and your son's 72 LT-1 restoration project progress. You have a great looking car that you should be very pleased with the result. 72 Fire Mist Ontario Orange is a beautiful color and worth the time and effort spent to get as close as possible match to the original factory color and finish.

I also have 72 LT-1 in Ontario Orange. It is a coupe with AC and still has its original applied from the factory survivor paint.

Re: 72 Ontario Orange paint question

If you ever get a chance to see Ed's Ontario Orange LT1, the paint is amazing. You'd enjoy seeing it.

Re: 72 Ontario Orange paint question

Ed, thank you for your kind comments. I'm fortunate that my son enjoys the rewards of our restoration projects. We have quite a few classic muscle cars, vintage trucks & hot rods (probably too many), however the rstoration of the 72 LT1 has been most challenging (and costly). Some believe our LT1 convertible C60 (#26756 build date July 21, 1972) could possibly be the last one (with the stated options) produced ? Maybe some day we will get the opportunity to see your very special survior. Best regards, Fred

Re: 72 Ontario Orange paint question

We re-painted our LT1 as part of the recent restoration. Current computer technology color matching was used to achieve a paint product consistant with OEM Ontario Orange in both color shade & metallic characteristics. Fortunately we used a borrowed windshield wiper grille from a un-restored Ontario Orange survivor 72 Corvette in assisting accurate color matching.

The single stage "color matched" 1972 Ontario Orange paint was used to re-paint the LT1, and we believe the re-painted finish resulted in both color shade & metallic consistent to a 1972 OEM Corvette finish. Recognizing and expecting to receive a standard deduction for paint originality/over restored related judging,

Obviously it wasn't possible to compare our re-paint results to one of the original "Color Standard" paint sample plates submitted to the St Louis plant by both Dupont and PPG for approval and quality control during the 1972 Corvette production period. Hopefully someone can help inform us regarding the method used by the NCRS to determine OEM paint originality.

If possible it would be great to know if the 1972 Corvette Dupont color chip 5293-L or 1972 Corvette Ditzier /PPG color chip 2358 paint chip catalogs accurate enough for judging purposes?

I will tell you how I matched Warbonnet Yellow AND will match ANY COLOR for a car judged in the NCRS. FWIW Warbonnet, Ontario Orange and Steel Cities Gray are all Firemist colors.

I took my original 1971 dealer album with the large samples in it to FINISHMASTERS and had it scanned, then I had it color corrected to the formula. Next I had them drop 25% of the metallic.
Did sprayouts sent them John Ballard,
Still too much metallic. dropped to 3 different contents 27%reduction 30% reduction 33% reduction in metallic
Resent samples to John Ballard -
Settled on 27%
This was shot one single coat of base followed by
2 coats of 50% color 50% clear reduced 25%
One coat 25% color 75% clear reduced 25% with 15% flattener added
& one of pure clear reduced 25% with 15% flattener.
The flattener causes the clear to look less plastic appearing.

The car lost only 5 points for too much gloss at the 2019 national show. No points against the color or application.

FWIW here are a few DETAIL photos of an original paint 1972 Firemist Ontario Orange LT1 from the 2019 Nationals
Approx 1" x 1" detail

Re: 72 Ontario Orange paint question

Here is a 72 ZR1 at the 2019 Cinci Regional show which was repainted in OO. I believe Jim Anderson owns this car and if not mistaken Gary Bosselman told me his son painted the car to the spec he (Gary) laid out.

Surface of the ZR1 paint - I saw this car and spoke with Gary just prior to painting the Warbonnet car or I may not have used the 15% flattener.

Re: 72 Ontario Orange paint question

Thanks for the responce. I know Gary B keeps spray out of cars he's painted, maybe I can compare his spray out to our paint.

Re: 72 Ontario Orange paint question

Sorry I was tardy on the reply, I have not been very active on the boards in the last 2 months as I am finishing a Camaro restoration for a customer plus was prejudging and prepping 2 never previously flighted cars along with my LT1 for the Greenville Regional this past weekend.

Of course they both did better than my own car...which lends credence to the old saying; "the cobblers kids never have shoes."
