Source of blue tinted paint on underside of '67 Los Camaro floor

I am confused.  You said this earlier.

I recall seeing blue paint over 2 coats of gold and under2-3 coats of white in some places I stripped

Is the blue definitely UNDER the gold?

Back in the 80s we restored a few cars and took them down to bare metal with soda blasting.  And recently my nephew decided to take his previously un-restored 69 down to bare metal and shoot with epoxy primer etc.

After almost 60 years, a lot can happen.

That was in reference to the pic I posted of the 3 colors in the cowl... not the underside.

I feel pretty confident that the car was repainted at some point with the blue paint. The fact that the blue is over the gold in the cowl area supports that.

Ok so, the blue being inside the shackle bushing tube and under the bump stop, while seemingly unlikely, could be explained away if they were indeed removed for a paint job. But how does the blue get under the factory undercoating?

Has there ever been a case where a car was painted a color, perhaps the wrong color, on the assembly line, then ran though the paint stage once again when the mistake was discovered? Then once the correct paint was applied, in this case the gold, "then" the undercoating, bump stops, shackles, etc,...were applied or installed?

[bcmiller]

Possible?  But I don't know of any cases of a car color being changed in the assembly process.

Are we even certain that's factory sound deadener/undercoating on top of the blue paint?  As stated earlier, a lot can happen over the years.

What appears to be dirt on the coating is Gold overspray. I cleaned that area twice with Simple Green, just to be certain it was paint and not years old grime.

 Didn't John Z once say that it was common when cleaning spray guns to spray under the chassis? Not sure where in the process that was done and if the LOS plant did that too.

 The wheelhouse undercoating was applied after paint at the factory. I see blue but no gold beneath the undercoating.

My brother and I stripped his 69 with trim tag showing white. The car had a repaint done in white but when we took it apart and stripped it we found traces of a similar blue in the package tray and other hidden areas. Not on the bottom I remember. It was enough for us to question the trim tag as to original to the car. The vin and tag numbers checked out and rivets looked untouched. It was an 04 Norwood X33. The interior was black.

I am a former owner of that Mountain Green car certified at MCACN.  The blue on the underside of your February car is more like a purple and not anywhere close to the same shade of what is under the Mountain Green car.

I read JohnZ's write-up on how Fisher Body painted vehicles and he noted that cars requiring major repairs would be routed to be repainted:

"If a unit required a major paint repair that couldn't be accommodated in the normal in-line cycle time, it could be diverted off the main line at the end of the repair booth into a parallel loop that ran in the opposite direction and fed the unit back into the main line ahead of the main repair booth; the re-run loop could accommodate about 20 units."

I started working at the Van Nuys Plant in 1978 and never heard of a car being repainted another color, but who knows what happened when they began to build the 1967 Camaro.  My 1979 Trans Am that was built at Van Nuys is painted Solar Gold and I can see gold paint on the under body that isn't covered by undercoating.

From JohnZ’s assembly article.

"Every time that consecutive cars had different colors, all of those guns had to shoot thinner from the manifolds to the guns (through the floor grates) to clean out the previous color, then charge the line with the new color before they could spray again, and that had to take place in about four seconds."

Put the body on a roto and cleaned with Simple Green. The paint is everywhere, even under the rear brake hose bracket and hard line clips. If this is not factory, someone did a hell of a job stripping this car to the bare shell to paint it...
Jon, the color in the first pics isn't accurate, as I was laying on a creeper under it and the lighting was poor. With the body rolled up, into the overhead led lights, this is very close to the pic of the Z car, but there is much more on mine...

I don't know what to tell you. Hopefully others see this and respond.
