been thinkin this myself but the badge black and the black plasticy bit behind it red mine is a black LCR btw
 
did u mask everythin else off? so u didnt spray the slats or does the bits i wanna paint come away from the grill?

The chrome S badge and the chrome surround comes apart. You end up with three parts... the S, the surround and the black slatted part.
 
No you don't need to take the bumper off, remove the plastic strip on the landing panel and then you will see how the whole S badge / grill assembly unclips.
