Coloring the radiator

Hey guys...just wondering if any of you have spray painted your radiator. I have the MAch 1 grille delete and I just thought it would look so much better if it looked purely black behind it instead of shiny aluminum. Not sure if spray painting it though would fuss with the air flow coming in.
 
you could paint it. i would take it out to do it (because if you spray paint through it you will coat your engine with overspray) and just give it a quick coat so as not to plug off the air passages with gobs of paint.
