Can anyone recommend a technique for hanging gator board. I have a 120"(L) x 38" gator mounted photo that is being installed in a corporate location for a 6 month period. The idea is that a new piece will replace it at the end of the period so the client wants to avoid repeated "damage" to the wall (yes they are uptight). I was thinking screwed in z-clips but the client keeps insisting on hook and loop. Any ideas?
