I am having trouble matching code 975 on a 1970 Coupe. We tried scanning the original paint from under the door plate and carpets but could not get a good read....Anyone have the formula or know the best place to get it or the paint.

Jan 1970 P&A30B Corvette parts catalog says ..
Marlboro Maroon: Lucite 5131-LH; Rinshed-Mason A-2280M; Ditzler 71584.
Only caveat is that Chev code listed for Marlboro Maroon is "77", not the trim tag code "975".Comment

John,
Unfortunately, even factory pack colors are likely going to be as inaccurate as that mixed at your local jobber. Factory pack paints are basically the same combination of mixing colors found on the jobbers charts but are mixed a bit more accurately. In the case of nearly any maroon metallic, the factory pack will be far from the original color on the car.
Most colors, especially metallic colors, are a hit or miss project. The computer match colors are a lot better than the old mixing charts but still not accurate, for a number of reasons.Comment

Check this thread awhile back
I can tell you the sample I have is dead on matched to a 70 original paint car I compared it to. I'll dig up the info maybe you can get the color you need

Thanks Dennis,
That looks like something other than commercially available factory pack. It's possible that some colors are dead on, or so close that they pass. However, for some colors, unless you have the exact same material that was used on the assy line, which was not available to the public, your chances of a match are near zero for most maroons and several other colors.
There's a long list of reasons why service paint will be different in chemical makeup and color than anything that was ever available to the public.
Try getting any factory pack Milano or Marlboro Maroon, from any supplier, to come anywhere near the original color.
My point is, don't waste money searching for/buying factory pack paint thinking it's the real thing. It's not.Comment

Don't know what you mean by factory pack paint.I agree with your explanation of the lack of abilty to match any color based on original formulation, or painting procedures for that matter. Guessing you have first hand experience and know that some colors were difficult to match for repair even after leaving the line. Also agree that to think paint could be matched for a repair is highly unlikely.
But, to paint an entire car, I'm still of the opinion,(and want to believe), that the best way to duplicate color is to have a known original sample plate,which is what the factory used to match paint, brought to and scanned under the industries newest technology and ideal conditions.Comment

Dennis,
For a time, after the new models were released, most of the paint manufacturers sold what they called "factory pack" paint. It came in containers labeled with the paint codes and color name. Judging by the printed label, i think everyone assumes that this is the real thing, the very same paint used on the assembly line. It's not even close. When thet refer to the word "factory", they mean the paint supplier, not the automobile manufacturer.
The basic ingredients for assembly line paint are almost completely different than those used for service/field. The binder, the goop that is the base for the material is made differently to be a baking/reflow formula. The fluidizers in it are set to go off, or fluidize/reflow, at a lower temperature. That's why a Corvette body comes out of the bake oven with a much better shine than it had when it went in.
For obvious reasons, cars can not be baked the same way in the field as many interior parts etc would begin to melt.
Paint made for service, or body shop/aftermarket use, is an entirely different binder, or base. It's called a "buffing/polishing" formula. (or something close to that) The fluidizers kick at a higher temperature. Too high to use in a bake oven. While a bake oven will help to dry the material faster and provide a harder surface, it does little for gloss/reflow.
OEM paint color is produced by what they call "single pigment" formulation. One ingredient produces the final color. In service, the color is matched by the paint supplier using as amny different colors as required to match the original as close as possible.
The reason this is done this was is the fact that no paint mfg warehouse could possibly stock all of the different colors for all the different vehicle mfg's over many years. this way, a small number of mixing colors can be used to somewhat match any OEM color.
Unfortunately, none of the records for specific pigments on old colors remain today. All of the paint mfg's toss all of this information at, or soon after, the end of that models use of the color. Each color used some unique ingredient to produce a color and unless we can figure out what it is, we have to mix several different colors to come close.
So, next time someone offers to sell you a few quarts of "the real thing", take a pass, unless it's cheap. Chances are it won't be close to the original color.Comment
