Location: bishop, ca | These photographs are from my collection of restoration and production research, as conducted with Greg Leggatt, of Napanee, Ontario.
Greg might not be the best pure-restorer of 57-58 Dodges, in the world, but, the term "meticulous" to describe his work quality is an understatement.
These photos detail his examination of how a hood was installed, and finished, and these are his handwritten captions.
Note how ineffectual the OEM "alkyd"(oil-based) sealer-primer was, in protecting the hood underside from operational deterioration.
Makes you appreciate what was occurring on/to the floor pans of a non-undercoated car, having only that sealer-primer, and some body-paint overspray, to protect the car from literally everything that the car would drive over or through!

Location: bishop, ca | And, oh yeah: the last photo shows Greg's restoration of a '58 Coro 2-dr HT, and his reconstruction of the application of OEM undercoating, with overspray onto the hood hinges.
Despite his best efforts, modern/aftermarket undercoat mastic does not compare with the substance and quality of the OEM material.

Location: Under the X in Texas | I'm going to stand up for the application of primer sealer on some of our cars some of the time. I had a '57 DeSoto Adventurer Convertible. Built in Detroit, never tar undercoated except the standard wheel well only coating. I bought it about '94 or '95 with around 55,xxx miles on it. It had been in S. Calif half its life and Arkansas the other half though that was mostly in storage. On that car I was able to wipe down the entire underside of the car with kerosene until it was clean, let it evaporate off, and then literally hand waxed the bottom side of the floors. They are beautiful in semi-gloss gray. Yeah, there was a bit of patina of surface rust beginning here and there but nothing at all major. The car has since received a restoration and is in the Milton Robson muscle car collection in Georgia near Atlanta. I have not seen it done in person and don't know what they did, if anything, to the undercarriage. Attached pic is of the car just prior to my selling it. Yes, it was a multiple special order car that had never had the hood ornamentation, had both dash clock and steering wheel watch, and had a limited slip diff.

Location: bishop, ca | I'm sorry, excuse-me, Wayne: WHERE did you say that that car had lived out its life?
In the wilds of AR & SoCal (AND in dead-storage--I know of that state )????
Now there's a tough life!
Kinda like spending your Viet War years stationed stateside, in the National Guard.
YEAH: I'm a veteran!
BTW: my own car survived Northern INDIANA . Now, THAT'S combat duty; Extinguished Service Medal, with rust- hole clusters!
James; that's OK; the pics got posted.

Location: Lemoore CA | Once again because I forget, what is the difference between cars that have the gray mud paint on the underside of the hood, and the ones that have body color? I noticed John sprayed the underside of his wagon hood body color. Is it a Detroit versus LA built car thing? |

Location: The Bat Cave, Fairborn, OH | The 1957 DeSoto is very nice, but I thought they all had a hood ornament from stock no matter what the series? Did you remove it when it was in your care?

Location: bishop, ca | As far as HOODS are concerned, it appears that CAN-cars did not have any body color applied to the hood's undersides; US-cars got body color applied all-over the underside--notice how there is NO gray-primer showing anywhere on the Coral-hood, not even at the nose of the hood.
That lightish-gray color is the shade of the OEM primer-sealer, which should also appear (along with perpendicular-angled body-paint overspray put down on top of it) on the under-sides of NON-UNDERCOATED floor pans.
On undercoated floor pans, the mastic stuff hides the primer/over-spray appearance (and also protects
the floor pans!).
As far as the TRUNKS are concerned, it appears that, in L.A. (and in Newark?), for DODGES, the paint booths were allowed to apply a generic mixture of all-the-various leftover exterior body-paints which were comingled, onto the trunks' undersides; THOSE colors are seen to vary among shades of blue-gray/blackish, much darker appearance from the OEM primer-sealer light blue-gray color.
Detroit-built Dodges had their trunk-undersides be painted in body-color.
I was dismayed (bfd), to see that John had stripped off the OEM hood undercoating, but, he COULD
righteously, now re-apply undercoating over that new body color, because that is how the factory did 'it'.
John could have, merely, stripped/sand-blasted/prepped the hood underside, while LEAVING
the undercoating intact, and then he could have applied the new-color to the hood underside. He could, then,
have touched-up the OEM undercoating with new material, as necessary, and/or re-painted the OEM
undercoating with gloss-black paint, to restore its as-new appearance.
