I haven't taken care of that yet, I have some fabric and resin laying around that I was going to use when I put mesh backing on. I wanted to see if I could utilize some of the gaps to see if the mesh would be secured by them in some way......
I also want to cut the center but then you loose structural integrity, so I am still coming up with a piece that will sit behind the mesh but keep the whole grill rigid, if that makes sense.
I also need to find some mesh that isn't tacky, gutter mesh is ghetto.
