In prepping the interior for correct overspray patterns (black charcoal metallic from dash, primer and paint overspray) I found the rollcage to B-Piller bolts to have an unusual head color. They are similar to lap seat belt bolts, but with a 13/16 hex head and an "N" in the head's middle. I believe these are 382873-s100.
This seat belt anchor style bolt is gold dichromate, then a shiny cad or similar is found on just the head, then the head is again covered in a dull zinc (appearance).
The dull zinc appearance is definitely a coating, but will scratch with an awl.
What exactly is this coating?

I have only seen then Zinc Dichromate.
Just to be on the safe side in your opening post on this thread '67 Shelby's, you state interior and painting it black - you do know that the paint black is really dark metallic charcoal; gray - right?

Yes! My bill from Wesco Auto Paints for a pint of charcoal metallic for $100 attests to this! But a pint mixed at 1:1 paint/reducer goes a really long way, considering how lightly it goes on.
But it's a valid point for those reading this and I updated my first post.
For others wondering what I'm doing, the floor and trunk was repainted by a PO owner to semi-gloss black and he put this stuff everywhere.
When I stripped the outside I also stripped down the inside and repainted all the sheet metal back to red oxide.
I will now dust on primer, color and dash colors in the proper order so the inside of the car replicates production order of these paint layers.
Jeff and Bob G. have been very helpful here.
It's an unseen detail, but I've gone this far ...
Thanks for the reply, Bob.
I would say the zinc dichromate has weathered off the head of the bolt from exposure leaving the zinc. The rest of the bolt has been protected and is still gold colored.

I saw the dichromate and thought that perhaps they didn't want something that bright and shiny up there and wanted to hide it!
But I like your thought process.

I think one of us has mentioned it before but it stands repeating . The dark grey metallic goes on very thin and requires multiple coats to cover by itself. Many have found it useful to first put down a base coat of semigloss black before spraying on a top coat of the proper dark grey metallic . This allows for less coats to cover. The grain in the doors or interior trim can easily be filled with too many coats.

Excellent pic. Thanks.
