do it man! me and a friend made a custom mesh grille for his focus. we picked up this metal mesh material at lowes and some support bar for the basic shape: (cellphone pics)
I know exactly what he is talking about. Its called gutter guard and its cheap! Ive used it for grilles before.
a tig welder would come in handy, i tried tacking the mesh to the support bar with a mig and it burned through even on low amps lol
