How should the under body of a 65 GTO be finished? A friend just purchased a 65 project car. The previous owner had started the restoration. He painted the under body in body color. Is this correct? did the finish vary by assembly plant?

Thanks in advance

Not body color.

It should be primer (either red or black, depending on final assembly location) with varying amounts of body colored overspray around the periphery.

Assuming that you want a "factory correct" restoration.

If you want a clean, driver, resto-mod then full body color is probably a nicer result.

It is going to be restored to factory correct. It came from the Pontiac Assembly plant.

Are you using factory correct nitrocellulose lacquer?

Doubt he will go that far. The goal is to look factory correct within reason.

At the Framingham plant in 1972, the primer was a maroon red color from a body dip tank.

Paint was applied my 2 guys is a paint booth, and the car was baked to reflow the paint.

Quality and coverage was just O.K.

I went with chassis black on the underside of my 64 and I’m pleased with it. My exterior color is Cameo Ivory and I just couldn’t envision the car all white on the underside. Personal choice/taste I guess.

Which process was used at Pontiac, red primer or black finish?

Thanks

It all so depends on your build sheet. Some cars got undercoating as mine did.

Here are pics of mine .

the lower parts of the car (belt line) down were primed with black that was a harder seal coat. that was sprayed all over the outside of body. Then a red oxide fill type primer was sprayed over that as a tooling coat .

There would be some amount of over spray of both the red oxide fill type primer and over-spray of the body color under the floors. mainly on the edges or where the painter sprayed the rockers and lower quarters and tail panel.

The over spray is now accepted in GTOAA judging with no point deduction for what some think of as sloppy workmanship LOL

the red you see is body color . my car is red

That looks really good. Overspray is a part of the process. It should have always been accepted or extra points for having it.
