I did this in the parking lot. I'm on the road all the time so pulling the bumper wasn't an option til I get home. After seeing how it came out. I may just zip tie it from the back, leave the mesh on the outside and just to hide the locking heads of the zips. It helps a lot if you use long zips so you can get them all curled back through the mesh and have enough room to get them all started. Then zip them all tight and clip the strips. You'll have a least 6' left over.
