There have been many threads on EX-P vs. EX on Light and Dark.
Do a search and you can find lot's of opinions.
I have used both on my black metallic.
I found EX-P to be more clear and reflective.
Like I said before, the metal flake really shows through.
EX gives a deeper more wet look, but not as reflective.
In fact on my 10 year old paint, I prefer EX because it also hides imperfections better.
That's a good thing on black because they show so much.
I am going to use EX-P on my wifes silver metallic.
Both will look awesome on your green, just different looks.
Try both and you decide what you like best.
