Grille material

I was just wondering what the best quality material would be for use as a grille, in my case, the Blitz bumper.
I have been given many suggestions by people I know so far, was even told 'gutter guard' by one, and would appreciate any suggestions/opinions.

Thanks in advance.

go to lowes or home depot and they sell a bendable aluminuim mesh piece(10'by3') its like 10 bucks. thats what i done my kit with and it won't rust or fade
