AMT's plastic color choice makes me want to smash things.
That color is just "Gawd Awful" !
I have built many of AMT's Mustang's over the last 45 years, and I have never seen one moulded in that color plastic.
You may want to cover it with a flat Black primer first.
( If I were to paint it, I would start with a Gold color first, then deep metallic Green.... but only if you want it Green. )
