Title: Correct Paint Color Undercarriage 1969 Shelby
Post by: Frankdenver on November 19, 2021, 07:44:14 AM
What is the correct paint color of undercarriage of 1969 Shelby GT350? Is it same as 69 Mach I or is it the red primer finish? Thanks.

Depends on when car was built early cars were orange primer then batch paint started showing up. Just look in transmission tunnel area as thats the best area that should still be original paint yet.

The 69 Claude DuBoius> ? sp, 69 gt 350 Conv, had a med grey primer color.
Sold it to C Brown, I do not know if Chris changed the under body color or not.
That is the color that I found in many area's of the car.
It was the Maroon car Ed.
Respectfully,
John

My GT350 vert May 6th build: Notice clogged sprayer and dark charcoal is the mix that came out on my car that day.

My 69 gt500 (602) was built in January, it was slop gray.

That is the color guys.
Slop grey>> that is a good description>> ha
I wonder if the color of the car determined the color of the primer sealer?
The maroon car >> should have had red oxide if that was the case ?

Depends on when your car was started at the plant.

Best place to figure this out is your cars original finishes so look unless you or someone else has already removed the original paint in this restoration or another. There were a number of documented periods through the year where the plant reverted to a red oxide epoxy primer similar to what was used from the firewall forward on the front frame rails and firewall forward section

Now lacking any original evidence then you should look to other cars finished the same week or day as your car - identified through a Marti report

Thank you for all the replies. My car was repainted before I purchased it. It has an order date of 3/12/69, and release date of 4/2/69. Unit number 481925, Hertz car. Appreciate any additional information.

Jeff,
The 69 Vert Chris bought from me was sent to Claude >> in Belgium>> Carrolls importer.
I brought it back to Georgia port in US.
it was like # 750 or maybe # 1450 ? both are just guesses, registry will show though.
One thing that was real weird, it had a serial number stamp on back of the head, not block, and was actually 2 numbers off on last digit, go figure.
It was the born with engine.

All is to the best of my recollection. Decades ago !!!

Dan can you describe the gray? Have a few others a week or so from your date and wanted to compare

It was all the leftover paint mixed together which came out various shades of gray. My car was unrestored when I bought it and the undercarriage was graphite gray, I've seen lighter and darker when I was doing research.

Understand and thanks for trying to help. Have a fair amount of pictures and floor samples cut from floors all with (well most) with VINs. Was interested in what the Dan found on his specific car since we find trends and patterns in the findings once graphed and compared.

Thanks that really helps narrow it down and your in luck since I have records of another 69 GT350 Hertz big suspension completed on the same day.

On that example we found the typical red oxide epoxy (not the flat Rustoleum look) applied on the bottom of the front frame rails from the firewall forward. From approx the firewall rearward a medium dark gray with a blue tint to it. Have other examples built a few days later where we find a change in the color and look but don't want to get off or focus - your car.

For that car we reproduced the color using a early 2000's VW exterior color with some blue added.  Was really happy with the color and look

From a picture I already had in storage on line where are just some of the examples of the blueish tinted grays we find on 69 Dearborn built cars. These are only single examples and the finished could differ a bit based on what the majority of exterior colors they used the day or days before.

Now the color you see on your monitor is likely different from what the color was originally due to digital camera settings, monitor settings and so on but it might give you a general idea. Closest for comparison to what we found is in the lower left corner below

The paint inside my, 68-01107 bellhouse covering is pink. 68-00202 is also.

The back of the car it's almost indescribable. It's encrusted with almost a dipped galvanized color and texture?

There is red oxide on it here and there but it is almost Rustoleum redish brown.

So the point is, duplicating those original paints is very, very difficult and many just give up and shoot the entire thing in red oxide which does really look nice but calling it "original" to me is taking poetic license.

I plan on uncovering mine when the weather breaks to start on my retirement project. It was built 2 days after Dan's so it will be interesting to see what I find.
Jeff, I take it the January pic is Dan's car?

No don't believe so. If its the Dan I think your referring to that was a later car (April)

We are in the process of refinishing the engine bay of my car, which was built in late December 1968.  It is slop gray (dark charcoal with a blue tint) with what appears to be traces of red iron oxide underneath the slop gray in some locations.

On my car at least 1 sprayer was clogged so I painted the whole underside Candy apple red single stage in my garage. I can always shoot some custom "batch paint" on it in the future. I'd like to see anyone actually duplicate the paint on the underside of their cars exactly.

If you start with a really nice unrestored car some are cleaning and scuffing the original coat on the undersides then just top coating a matching color over the original so that you retain the original drips, bubbles and runs. Have been able to do this on a few cars

Of course this can't be done on many cars after all these years so many just try their best

In the case of the later cars that were painted with batch paint ,unless you match the underside paint to your individual car the term "exactly " may not be relevant. More like "what is expected " would be a better usage in this context. The mixture of the paint changed from one batch to another with no two batch's exactly the same .There is a wide range of possibilities in the case of the batch paint used when redoing a 69/70 Shelby underside . You probably already know this now as your detail knowledge increased but for those others that may read this now and in the future the convertible tunnel crossmember seen in the example picture is also a batch paint typically different then the shade used on the floors. It is not black in this Shelby context as it appears in the picture.  There is no cut line between the engine compartment black and the underside . It faded from black to the underside color. When the assemblyline paint man sprayed he only did it as far as he could reach into the tunnel and underside with no concern other then blacking out what you could see from the top side looking in. Gary restored his cars many years (a couple decades?) ago .

I learned a lot since I restored my car but my pics above was the batched sprayed met charcoal black hue on May 6 1969 Dearborn assy. I think you know my good friend Seraphim's April built 69 Boss 429 is a great learning point for me on the dearborn assy line build. His car came out a mauve/gray(depending on the lighting). I have not seen 2 colors alike(chances are slim to find 2 cars still having that built togather) on all the original paint undersides I have found. My rust free indian fire red SJ 69 May 13 1969 R-code Mach1  looked to have indian fire red underside when I stripped the sound deadner off the floors early 90s(real close and metallic to boot so I thought the underside was painted IF red). Since I don't think I'll ever sell my vert red was my preference. Looks GREAT and I can always take the points deduction like with the white stripes on it. Gary
