So if my Eminger & Marti report show a January 8 build date, is that when it was built at Dearborn or AO Smith?

Eminger/shipping invoices I have only show when the invoice was prepared not the real build date. Look to the Marti report for that


This would be red oxide underneath?

Can't be certain but if data that has been shared of cars built before and after Jan 8th were batch from firewall rearward and red oxide epoxy sealer from firewall forward

I think itís important to understand for those who donít know there was no primer called slop gray that was used initially. Slop gray came about as a result of mixing leftover body color and with a primer to use it up and extend the use. So at the beginning of the model year and then again we see in January sometime the vats were started with red primer and then through mixing the other colors in as an artist would know everything would turn towards black or in this case dark gray. Depending on when other colors were put in you can see some crazy wild undercarriage colors. I have seen purple and green

100% correct, my gt500 slop gray was dark and had lots of metallic in it. Rust Oleum graphite wheel paint was almost an exact match.

I have seen a in your face Maroon color as my wildest color seen. I am sure there are others but to be clear to others reading for direction they are in the small minority compared to the predominate gray as has been described .

God point Tim. Can see where newbies might think we are describing a specific color name.


As an aside concerning the colors that can be referred to as slop or batch color as mentioned its typically a gray - medium to very very dark often with some metallic and either a green or bluish tint. When you start seeing some very "different" looking colors in 70 Dearborn Mustangs with the introduction and popularity of things like brighter and flashier (thing Grabber) colors

Then when you mix that with a contrasting body color over spray you get some very IMHO unpleasant combinations. Thing Grabber Orange with a light green under carriage. In other cases the color or tint of the undercarriage color is fairly close to the exterior color, leading some in the hobby's early yes to believe that their car had body color on the exterior and under

Not sure why we forgot to post this link. It might help as well as offer some examples

https://www.saacforum.com/index.php?topic=929.msg6979#msg6979

Also thought I would post some examples of the some of range of what the mixed colors produced. There are even odder examples but thought I would stay, at this time, with the more typical colors or tints found. Some of these are from cars O took, others from owners and shops and finally some are from samples of floors I cut out and save in bags so that I don't have to rely on pictures with varying lighting when I can get a sample








Of course have plenty more :)

And some of the examples of the range of what the red oxide color follows were. Notice in both the grays and the red oxide that these are not flat finishes originally though with exposure to the elements they can get that look on some samples. Take notice of the reflection in the one well preserved examples
