Believe it or not I used 20 lb fishing line. I tied it in 5 different places. the corners and the center. I cannot even notice where I tied it. I thought zip ties looked to ( sorry to all the guys/girls who have done it) tacky. I tried to make it as invincible as possible. IMO black would not make it more see-thru. Plus painting it black defeats the purpose of making it silver since it's already black behind it, but to each his/her own!:m2:I am thinking of doing this but painting it black before I install. Its a little more see through but I think it will look really slick. How dod you attach it? Zip ties?
