What is the correct color for factory gray underside paint (84 in my case)? Why did some cars seem to get a heavier coating of body color paint on the underside?

That is a great question. Not sure I know the answer. It varied over years. I too would like to know

I would like to know as well. I have been trying to figure out how to match the color since there is really no good way to take a "part" of the car to match.

Add me to the collection of people who want to know more. I am in process of re-working some undercarriage detailing and would like more/better info. I will be at the point of deciding how to proceed within a week or two.
I just looked at some undercarriage pics I have of a low mileage 84 GT350. The pics aren't that good, but there is one clear shot which shows the floor pans. They are a silver color, much lighter than Saturn V's example. However it kind of appears other pieces on this car may be closer to this darker gray.
Perhaps one of these days we can document all of these details on a variety of unmolested cars............

I had a medium gray metallic 79 that had black primer on the undercarriage and engine compartment. I wonder if these aren't like the 60s Mustangs and their "slop" primer made out of leftover paint.

Our early 79 Tangerine coupe had black primer under the single stage paint from all the indications I've seen. Also underneath the road abrasion and undercoating it is black underneath.

I wouldn't be surprised that primer colors varied by year. My '86 SVO is a gray primer. but the 2R body color is evident over a lot of the underside. While my car is undercoated, I have removed some of it above the rear end that I restored. The gray primer cleaned up really good, but the body color over spray came off with the under coating.
I have pics of Daniel Carpenter's low mileage (non-undercoated) SVO's ('85.5 and '86) and both are gray primer with body color over spray. I have pics of another low mileage '86 SVO and the gray primer has considerable body color over spray. Lots of neat details when you don't have the nasty under coating all over everything!

Wow. That's a terrific looking undercarriage. Provides us lots of details to work with, including..... more blue-painted nuts!!
I am working today under my car, doing some detailing. I will post up certain findings when I get a chance.

Now that is well preserved.
Excellent shots for documentation.
The early version long chrome OEM dual tip tailpipes.
Muffler in/out loc.
Drive shaft code paint rings and other paint markings
Wonder if the two plants at the time sourced slightly different material in the dip tanks?
Most i seen the under body a greenish gray, even on the newer ones.
Not mine though. Not a trace of gray. Was undercoated.
For the record; is the pc in pic V8, 2.3, auto, manual? DAP or San Jose?
Prob a V8. My 79 turbo has dual fuel lines (one is return from pump).
if you paint the underside color matching will you get marked down in judging?

That explains why the under carriage of my 79 notch San Jose car is black. Always thought the PO painted it. Guess it was from the factory
Unpainted dolly mounting points..... I'd like to see the pics.

Here's my two cents.
I am reworking my undercarriage detailing, working the floor pan areas as we speak. I did them about three years ago, now re-doing them to do a better job and to incorporate more details such as info from the ultra-low-mileage Pace Car above. After lots of work and study, I am convinced mine also had a black coating/primer. (Aside: It is interesting how the effects of undercoating, road abrasion overspray, 36 years of road grime, and 36 years of wear and tear all play a part.)
So I'm consistent with several posters above, but not with 79mustangcobra (!).
I think I am going to go back with Eastwood Chassis Black Satin, which I used before. It looks to be a pretty good representation, based on the info & pictures we have (though as bluemax points out, one can't take a 'part' off for paint matching).
This leads to the next question: I was able to find a small unmolested area on a frame rail. It is definitely a gloss black. So I am wondering, could the floor pans and frame rails be different finishes (pans=satin, rails=gloss)? Is this plausible based on the manufacturing and assembly procedures in place in 1979?

Did come across black and white photos of 1978 Mustang II getting primed.
Stated as a new system, can assume it was in place for the Fox gen.
Not unreasonable that the frame rails were touched up later on in the plant.
There should be areas of primer? E-coat? color inside the car that have been protected over the years.
Or missed by paint.
Behind rear trim panels, inner wheel wells, spare tire well, etc.
All is see is black everywhere in my car, a black car.

That looks darker than what is on the low mileage '86 cars I have pics of.
This is a good shot of the fuel filter. Again, notice the dolly mounting point. You can also see the white overspray (9L car).

Mine is the true gray color too. 86 GT I ordered what I thought was the correct color; but it is not. Attached is my original rear undercarriage with the exception of the new "RELOCATED" rear main brake line feed. The line follows my welded in frame rails and comes up along the frame directly under the master cylinder mount. A ford motorsports manual proportioning valve will be mounted either on the inner fender or firewall. (see Attached)
