Olivedrab Chromate Coating

Specified for this project are cadmium plated and protected with olive-drab chromate coating in accordance with FS QQ-P-35C [link is to spec at TechStreet], II, class 3. Is the olive drab coating of any use without the chromate coating? And would you have the same or equivelant protection with the chromate coating without the olive drab?

The 'olive drab' IS the 'chromate coating', Mr. Jones. Chromates are available in clear, yellow, black, and olive drab (and perhaps a few more obscure shades). Of them all, the olive drab chromate affords the most corrosion protection.
