I just found this article while researching weather Gorilla Super Glue is good on 40K models and if the results are true.... I am IMPRESSED!

Warhammer 40k, Fantasy, Wargames & Miniatures News: Bell of Lost Souls: Terrain: Gorilla Glue and You!

Has anyone tried this? I will gladly give it a go if it actually works! I've been looking for a way to make modular terrain without particle board, so this is perfect.
