Best way to paint the outer grill?

[In The Ten Ring]

Sorry for not having pics, my computer has been on the fritz.

So I am about to remove my rusty and crusty original grill brackets and while those are off, it would be a good time to paint that black line that goes around the grill (mine is all but worn off). What is the best way to paint that on including what paint?

I was thinking about roughing the area up a bit with steel wool, taping it off, and then spray painting on some primer and then gloss black. What say you?
