Ok engine bay is just about stripped of its parts and ready for paint stripping and repair some screw holes and rust under battery tray.
But there are some questions on the paint finish on bay, Outer bay panels, Bottom of the chassis rails.The car looks to have had the engine bay painted before the outer panels not real sure on that maybe some one can tell me that from the photos and the bottom of the chassis rail looks old and hard to tell as well. Its a 1970 Mach1 11/69 Dearborn car.
Lets start with the bay it looks like it was painted black over bare metal then red oxide and then black again the first coat could be the original factory layer but not sure if the whole bays are red oxide first then satin blacked.
Looks to me from the picture that you have red oxide (likely only in some places and bare steel in others) them the engine compartment black over that. Top exposed color is really the main focus since its the coat you'll see on the finished product
The top section of the firewall would it be satin black like the rest of the bay and would the black go all the way up to the windshield or does it stop just under the wiper panel and then its just the body colour to windshield?
The top of the cowl - looks like possibly two different applications of black especially considering that all the mounting hardware for everything under the cowl cover is black and the engine compartment black was applied long before those items were installed
With the outer panels the sound deadener is flaking off and under that it just looks like thin black paint. On the drivers side under one of the steering box bolts theres a small amount of yellow/gold over spray.
Is the yellow gold (looks greenish on my monitor) a match to the exterior color? Easy to see that someone in the past got in those wheel wells with a black spray can covering things.
Would it just be all black with maybe a bit of over spray from the body been painted then the sound deadener over that? I know its a little hard to see but does the sound deadener spray pattern look to be right? I do have more photos if it helps.
Typically you will find the color from the bottom of the frame and from the firewall forward as a base (shot first) then body color from the guy applying that at Dearborn. They often painted forward to almost the rear edge of the shock tower, sometimes into the shock tower or to the forward edge - no mandatory place they had to stop. Because they seem to not have wanted to bend over on every car every time the edge is over tilted from the lower edge of spray forward and upward
Then the engine compartment sprayer did his job - inside of the engine walls, up and over the cowl, paint the radiator support (no identified specific order known) and they often wrapped the black around the edges onto the forward inner fender panels, on the outer surface. How far back they applied (or downward towards the frame rail on the sides was their choice at the time. Sometimes they were covering markings applied earlier to the panels or spray outs applied there by the body paint guy.
Now the bottom of the chassis would it be just black or red oxide? I have cleaned some paint off and it just looks like black over bare metal?
Likely allot has worn off from exposure and surface rust that has developed on the thin application. Looks like there is allot more there to clean. Pockets and vertical surfaces on small areas facing rearward might provide the best resource for a look at the original color and product applied Check inside the shock tower area also since the same product should be the base or above the red oxide if shot in there, in that area
