It doesn't look like they're doing a chrome basecoat for it.
For a moment it looked okay, but then looking up again what the Armorerer looks like, the finish of the EFX just isn't quite there. I wonder if it's possible to remove some of the weathering to bring up the gold underneath. I think the weathering looks fine, but maybe it's dulling the color of the helmet too much.
This helmet is very dark. The last photo shows the EFX with a T&A Workshop helmet from several years ago. I like the EFX, but it doesn't look as metallic as many expect.
