anyone know where i can get some good mesh that you can't see through, its soo annoying to c all the stuff behind cars with body kits and i am gettin one put on as we speak but i want to give them some better mesh to use

 

Most of the "good" mesh I have seen people have just grabbed out of dumpsters from machine shops. The best way to do it is get some mesh online or from the local hardware store (Lowe's sells a six foot sheet for something like $8), and get some screen material you see on a screen door. Cut the mesh and get it all bent and fitting nicely. Then cut some screen material (double it up even), and glue it to the mesh with some epoxi or cement. The screening material will then block out what's behind and still let air through.
