Rear Spoiler?

I got lucky. got a MAS spoiler from a friend for $20.00.
Has a chip on one corner. Still debating on using it.
I want to put studs through it and cover the mounting screw
holes. Hope i can make it work that way. Just to make it look
smoother. like the one pictured.
Don't know if I'm painting it body color or black.
What's your guy's opinion. Black or green.
