Ok so I went to the plastic company near by and was going to buy some lexan for my project ($300) and was advised by the local guru there that I should use high impact plexi 1/4" ($70)since I will be hunting with it as the branches and stuff won't scratch it as bad. He also said if I can mount it where it can flex it should never break unless it's a really hard small impact and also to change it every few years so here's what I came up with used Velcro cinch straps to mount it total about $80
