Looks very nice, so they used the "slop" gray primer instead of the red oxide on the '69s?
Depends on the time of the production year.
Got the old girl back from the body shop. Here are a few initial pics. Hopefully we got somewhat close to what the factory did!
Dearborn car built April 2nd
Since I'm guessing that you have already looked at the dozens of pictures that have been posted on 69 Dearborn sealant and painting details posted here on this site some of these details should be familiar
1- Looks like you forgot the seam sealer in the front wheel well and trunk that was originally covered with body color. Pictures #1, 3 & 4
Front wheelwell shot without the sound deadener was added over most of this surface - normally stops (sound deadener) before it reaches much of the outer frame surface. NOTE: that the vertical sealer application missed the intended seam - should/normally follows the inner fender to body seam to the rear by about 4-6 inches in the picture
Arrows show some of the seams that would have been sealed before exterior color
2- Front wheel well paint pattern looks similar to one of the many variations of course much of this will be covered with sound deadener once you get the car together
3- See you didn't reproduce the look of the original sealer in the interior- but no one will see that once the car is together Picture #2
4- In picture #5 normally by April at Dearborn the cowl above the firewall (towards windshield) on Mustangs would normally be blacked out with engine compartment black as well as those small upper filler panels between the rear inner fender panels and the top of the cowl. Would expect that Cougars had the same details like the cougar shown below (white exterior car)
5- In picture #7 - noticed that you choose not to reproduce the cars dolly marks. Intentional or an oversight? Your rear most one on the rear frame with be reversed compared to this 69 Dearborn Mustang example The3 Mustang dolly shadow would be forward of the Cougar (used) mark rather than this example where the Cougar shadow is rearward from the used, Mustang dolly shadow
Don't forget to black out the pinch weld
Your going to need to figure out if your model of Cougar had sound deadener applied to the floor pans from below - like the Mustang Mach I, some Boss 302's and Grandes
Hope this helps
