Use the meshing from Home Depot or Lowe's that is rust proof and black. If it's not black already, shoot it with Rust-Oleum and use a satin black finish.
Mount from the back side (obviously) and run a bead of gorilla glue or epoxy gel, which will hold in place REALLY good.
BTW - Where in MD are you? I'm in Fairfax, VA - 2004 NSX.
