Should the pinch welds be black or Smoke silver gray ?

Blacked out before any additional panels are added to the car. Near about the same point in the assembly line when the engine compartment, radiator support and such were painted black but a different station and process. This produced a little or allot of paint (with overspray extending inward) spray onto the floor and panels (such as front frame inward from the pinch weld) that hung down. If little the paint application was thicker since there was less area covered so the amount was greater with it did get sprayed.

This also produced a thin ribbon of no or misting of paint where the pinch weld created a shadow on the inner side of the pinch weld as well as immediately next to the rocker.

During the application of the pinch weld black out the gun/spray once it got to the front edge of the opening for the rear wheel well, would typically spray black onto the leading edge/area of the inner wheel well where the sound deadener and exterior paint had been applied at prior stations. The same thing happened at the rear of that some inner wheel well where the spray application of black started again to the rear edge of the quarter panel. This typically produced (in addition to it over the sound deadener and exterior color in the wheel well, black being applied over the rear frame rail directly below the wheel well panel and extending back on the frame rail 8-12" rearward. Often far enough back to be seen around the forward, outer edge of the bare (treated) circle left by the dolly the body was attached to at the time

Hope this helps explain the details well enough

Black, the book says to use "blackout" paint, but I don't know if that is a semi-gloss or a flat (or in between) paint. I'll guess at flat black, ref 65 Mustang Body Assembly Manual (AM0006 pg 28, N4-N5-8400, 66 is a different reference page). The book shows where - the reality may be different. Be advised the "blackout" effect is also applied to the pinch weld to the rear of the wheel well as well. It applies "to all models with light colored exterior paint". (That's a complete description for future inquiries, a practice that gets omitted by some.)

From original cars with even 50 of age it has always looked to be semi-gloss black and possibly piped from the same supply that they used on the engine compartment as well as front wheel wells at some factorys. Also that would keep costs down, one less paint to source, adds an additional set of piping and product to store on site.

Agree. Notable is that black cars didn't get this treatment. It's most apparent on white or yellow cars.

I should be explained for others reading that are not familiar with the subject being discussed that the black out procedure serves a very important cosmetic purpose. It was one of Ford's better idea's .   The ugly wavy spot welded union of the inner and outer rocker seems to disappear when viewed from a distance once it is blacked out. The pinch weld black out is one of the least expensive easiest things that a owner can do to improve the outside appearance of a car IMO.

+1 Once you know it was there and see cars done correctly, from then forward you eyes will check for that detail immediately and notice that the car somehow looks unfinished. That has been my experience an done communicated many times by others on forums an din person

Also (like body color overspray) a big pain to apply it to look factory after the car is assembled. Just faced that issue with an owner trying to better their car a few days ago.

It's funny how this (and others) topic gets asked here and on other forums at the same time. Kind of weird, huh.

Either shopping for "their answer" or they don't trust  a single source such as this site if the question is asked on multiple sites.

One thing  we didn't mention in this black out pinch weld thread is that the "edge of the paint" on the bottom of the rocker panel was applied so that it had a soft edge and not one that suggests that it was masked off but instead a moving mask or a very specific nozzle, angle, pressure as to produce such an edge. Many restorers reproduce this look but using a thin, over the tape or even foam tape to create the edge or use the technique sometimes referred to backwards masking where you apply the masking tape then bend, NOT FOLD, the tape back wards to create curve in the edge that will create soft edge especially if you can apply the black in a single pass
