Does Zinc Chromate come in a redish/brown color so that it could be
confused with Red Oxide Primer?

Reason I'm asking is I got the CD for the Tcraft I'm examining. It has
a 337 from 1966 stating "all tubing cleaned and primed with red oxide
primer".

Then I have a more recent 337 dated 1978 which says "Tubing zinc
chromated and preserved linseed oil". That appears to be the last 337.

Since I assume ZC is green, I'm confused by what I'm seeing - Mike

I have never seen red ZC. Normal ZC is a yellowish-green; the green
stuff has a bit of black added to make it olive-colored.
