That yellow looks REALLY bright, the left ESB shoulder IS chromate, while the knees are NOT. Union Pacific Yellow is not the same color its duller. RLM 22 is the same color however.
And I like acrylics as well for the armor...some people will say its not as sturdy but most automobiles are water based paint now....
Im still working on equivalents as I dont think testors is correct in what they SAY is an equivalent. Like US MED Green dries the same as (MM) Russian Armor Green. I can for sure tell you that like RLM 22 are colors I sat down at the hobby shop with their 3 racks of paint and figured it out with floquils in hand.
