Hot Glue Gun For Cardboard Strips - Model Railroader Magazine

I made part of a tunnel using a glue gun.  Yes, annoying to hold the cardboard strips down on the foam.  I then put plaster cloth on top before using Plaster of Paris to cover up any holes.  Afterward, I painted the area and added bushes (again with a glue gun). 

In short, glue guns have their place.  I also like that they are cheap and easy to use without much of a mess.  It also doesn't require a lot of brain power.
