A popular choice is Testors Panzer gray their stock number 1950,
U.S. Government Federal Standard FS36076
New family portrait.
Although it just looks like a little putty and, VIOLA!, they're done; there's a lot more involved than that.
The green one to the left is a badly damaged, poorly molded production piece that had been relegated to paint tests,
and the gray one on the right is a Golden Armor made helmet with spikey, blown-in fiberglass sticking out all over the inside.
I completely sealed and refinished the GA helmet,
and I had to saw cut the green one to lay new mat on the inside to correct it, as well as rebuilding external features on both.
Ohhh, yeahhhh, NOW I remember why I put off finishing them....
I'm finishing these up for inclusion in the new Firefly Fan Film, "First Meeting".
Lower quality pic, but the work is further along:
