All 67-68 XR7 lower dashes were painted charcoal, not just the G.
Sorry forgive me I slid back into Mustangs. Don’t have any pictures of Cougars with the A pillars blacked out (hopefully some one has some of an original paint car to offer) though I would not put it past Ford since they did black out areas behind panels and pads in other areas. But agree one the doors not being shot interior color now that you bring it up - some Mustang bleed over 
Cougar example
Mustang example
No shot as a unit - the painters shot the inside opening and surfaces then just closed the door and continued
Since the floor is a lower surface it got most of the overspray or direct spray. As you move up the interior of the car you will normally see less and less body color and more bare metal or primer (red or gray depending)
Everything was added later,
Getting a\heads of ourselves don’t forget that the body color gets sprayed over the rear wheel well sound deadener but not the front wheel sell deadener (it was added after the car was completed (minus front wheels and tires) the body color overspray would include the exposed surfaces of the frame and gas tank drop visible in the wheelwell
Since your doing a G not sure (sorry can’t recall ) if the lower color on tu tone cars got shot first (like later Mach I Mustangs) or after body color. This will effect the overspray under the car. Also don’t forget the pinch weld black out - and the overspray on the undercarriage - especially any panel that hung down like front frame rails, torque box …
Here is an example - though allot of the overspray is gone due to the elements
Are you sure… the shell I got had original factory paint and the dash was the color of the car, I’ve seen this elsewhere as well. I’ve been told it was just the Gs that had the whole dash charcoal grey but I can’t confirm. I’ll send Royce (runs the G registry) an email and see what he says.
Yes doing a G tribute. One other guy on this thread is as well that is asking questons so it might get confusing. 
I got the undercoating in the wells and proper over spray in the right spots. Just wanted some confirmation on the interior stuff before I continue.
Arggg, my painter is away for 6 weeks so I might just paint the car myself, I’ve done everything myself to this point so why not, lol. I’m now considering building a stokered 351W, i.e. 408 or 427 EFI. I’ll have to get on this this month.
In this shot, it looks like the paint went on rather heavy for it to have the runs. Did they run a strip of masking tape just above the bottom of the rocker panel when painting the lip black? I would imagine that the tape just hung down and not stuck down tight to the rocker to avoid a sharp edge.
No tape used from what we understand from the workers. But a mask or shield was used leaving a soft paint edge along the bottom of the rocker and quarter panels and nothing was used to stop the overspray long the bottom of the car (Ford wanted anything that could be seen to be black out under there if possible. Pressure on the gun was likely less that exterior guns and the angle was slightly higher. And since the guns were held much closer to the car (not doing show cars here) the overspray on anything close (torque boxes being the closest) would collect the most paint under the car.
Applied normally from the front of the pinch in the front wheelwell behind where the fender goes (not installed yet) to the rear valance bottom edge. This is believed to not have been done on dark exterior cars though a number of black jade cars have been found with it done. Also from time to time it seems cars got missed and the old coffee can, black paint and brush were used to do those cars later when they were caught down the line by an inspector - though very few have been found to have been missed so far 
Should add that many restorers use backwards masking (where the masking tape is applied backwards then bent back - smoothly not with a sharp edge) and then the pinch weld painted to produce the soft edge or others use foam tape rather than masking to produce the same effect
Hope this helps
Ok according to Royce all 1968 XR7s and XR7-Gs had the dash and steering column painted charcoal black at the factory. The standard Cougars had the dash and column painted to match interior color.
Ok another question someone might know. I was looking at the sunroof assembly and roof pillars on the 68 sunroof roof cut I got the sunroof from and it appears to have the same type of undercoating, (similar to a truck bed coating that they used on parts of the frame), sprayed all over the sunroof assembly and roof pillars etc inside the car. Since I only have a roof cut to reference does anyone know or have pictures showing how far they sprayed this coating? Did they only do this on sunroof cars for obvious moisture reasons?
Sunroofs were never sprayed with any kind of under coating during assembly.
+1 - never seen sound deadener applied to the bottom side of the roof on a non sun roof or sun roof example
Now that I look at it I have a feeling that it could be a lot of really old adhesive uses for the head liner, I’ll have to take some pics and post.
Not sure what to make of this grey stuff, it had the texture similar to hard bed coating and has to be ground off, maybe just happened due to age of whatever it is but it appears that it covered the whole sunroof assembly and inner roof areas. Appears factory but that mean nothing, you can also see the factory primer under where I removed the sunroof assembly. It doesn’t appear to be old adhesive for the headliner someone may have used but what do I know.
