I may be TOTALLY wrong, but I have a '70 AMX
that has the Shadow Mask paint.
AND I belive it to be the original paint.
It is not the flat black like used on the
'69 Mustang Mach I. It may be a low gloss,
but I belive it is gloss black.
The paint on the edge of the roof appears
to be the same as the hood. This car had
only 1 coat of paint on it when I sanded
the silver off many years ago, and the "mask"
paint that I have removed only had 1 coat.
I have been curious if it suppose to flat or
a gloss/low gloss.
It sure seems that back when I raced some AMX's
in early '70's that it was NOT flat black. I had a Camaro then.
