On the subject of Zip Ties, they work quite well with coroplast, I was able to make slits along the corrugation and run the zip tie inside the coroplast without coming through the front then tying it to whatever i needed. This is how I fasted my front fog lamp covers and grill block. The fog lamps used zip ties connected to an I-bolt this allowed me to get everything tucked where it needed to be then tighten the bolt from the back of the bumper (I had to drill a hole in the fog lamp holder spot but it's not too devastating).

The zip ties work great and allow for the modifications to be removed without any damage to the car except the hole in the blank fog lamp things but like i said, not too concerned about those. Also it provides for a smooth outer layer with no fasteners sticking through the coroplast.
