Testors had a formula color change sometime ago.. and before then I would say Floquil UP Armor Yellow... but the new mix isn't right according to color swatches (from a very good source). The closest color in my mind, after trail and error... is SP Armor Yellow (Floquil)... it seems a bit saturated at first, but once the weathering is applied it does what it's suppose to.
Here you go,,, this was taken early in the weathering process... so it's about half way done, but its the only pic I have.
