Making razor wire fences for Octarius | Fallout | Zombicide | Warhammer 40k 

I wouldn't recommend it, only because it shrinks after you apply it. It's basically pre-mixed greenstuff that you can apply with a brush, but it's lousy for hiding gaps on models. You're better off with normal greenstuff mixed with a little water (to make it workable), or go with milliput mixed with a tiny bit of isopropyl alcohol (to make it workable).

Yes, that was a decal from Green Stuff World.

I've often thought about using Lego! I may have to rob my son's Lego collection

Yeah I bought a bunch of screen to fix some old windows at my place then had a bunch left over. Now I just cut it up for terrain :)
