Sorry, Rufus. I don't mean to be rude, but the green metallic color is
an epoxy paint. The bronze color you see in photos of unpainted F-15s
and F18s is the anodized aluminum coating that you're referring to.
I've walked through the assembly line hundreds of times over the
years, and our IPMS chapter has hosted a couple of McDonnell Douglas
guys who worked in the paint shop applying the stuff, so I can state
with certainty that it is a 2-part epoxy that is mixed right before
application.

Being one of those McDonnell guys myself (that works in the field -
coming up on 20 years), I'll check with my Field Servce folks on Monday
when I get back to work. Like I said it's been awhile since I've been
in the paint shop, and I usually see the raw stuff applied in small
amounts when repairing/modifying jets (and I don't recall the shop guys
having to mix it up for such repairs, though). I think the undercoat
you're referring to is called allodyne...but I'll have to look that up
too. (I know the exterior surfaces are painted with a urethane
stuff...that used to routinely get all over our cars in the Bldg 42
parking lot...)
I'm thinking in terms of the process spec for its application (it may be
the allodyne spec I'm thinking of), so I may be mixing up specs. I know
the stuff is more durable than the white paint that goes over it on the
Navy jets. And Northrop uses it too - they make the back end of the
F/A-18 series and it's there as well. I'll also check to see if it's a
McDonnell propriatary coating...I'd be surprised if it is.

Hi,
Alodine is a brand name. Like Kleenex is for tissue.
AKA chem film, chromate, chromate conversion, gold chromate, yellow
chromate.
And the only one that really counts.
MIL-C-5541 Chemical conversion coatings.

Yes - and I'm no sure the same doesn't hold for the blue-green
primer...whatever it is. I know there are process specs for both of them.
